Steve Kelley sent me these comments on the Boston VMSK meeting he attended in Boston on September 22, 2000. They are posted here with his permission.
I was at the Boston meeting mentioned below. The demos were not conclusive, some worked, some didn't and some on the agenda never happened. There were a lot of unanswered questions. The attendees wanted to investigate further and AlphaCom took emails and promised to distribute an email list.
I sent out my conclusions from the meeting to the contacts I had (about 10% of total attendees), including AlphaCom contacts: the text of this email is included. At some point I came across the link to your site and sent that to my list as well: this email is also included. At this point Jeff Cutruzzula (COO of AlphaCom) and Jack Craciun III (Chairman of ITM Ltd.) threatened lawsuits, and made annoying phone calls to me at home, and demanded I stop communicating with the people who went to the Boston meeting. Jack Craciun sent me his conclusions from the meeting which are in the enclosed word document. [Here it is in HTML - Phil]
Anyway, I thought this may give you some more data on the Boston meeting and how much AlphaCom encouraged the scientist who were there to exchange information after the meeting.

I also enjoyed meeting and talking with you. In the interests of really understanding what went on at that meeting, I'd like to candidly share my views with you. I'd be very happy to hear any further thoughts or information you might have on the subject.
These are my (very conservative) high level conclusions from the VMSK meeting in Boston on 22Sep2000:
Marketable boxes for cell phone and FM radio frequency applications are probably at least 12 months out according to Van Dreimer, General Partner of Timberstone consulting group who are providing marketing assistance to Alphacom.
Hal Walker thinks microwave application will be out in 3 to 6 months. He says some filtering problems he is facing in the lower frequencies are not a problem in microwave.
The spectral efficiency and 120 bit/s/hz rate seen in the demos is amazing and reason for further investigation. Dr. Kamilo Feher is a independent reference for this statement. This alone is worth further investigation to see what is happening and how far these demonstrations can be taken towards making practical products.
However, nobody, including the inventor, has a clear understanding of where the information is, what tradeoffs might be being made, how exactly this works, or how exactly this may be incorporated into practical devices beyond the demo. A simulation of the phenomena would be a good step to addressing these question. Whether several such signals can be put close together and resolved without interfering with each other to realize the promise of the spectral efficiency is also not certain.
In summary, there is a very interesting and promising phenomena here, but no solid evidence yet of the ability to produce marketable products with the claimed 20-30 times greater bandwidth the similar products.

At the 22Sep2000 Boston VMSK meeting, there seemed to be a general agreement to distribute a mailing list of participants. I'm enclosing a spreadsheet combining information obtained from Jeff Cutruzzula and myself. Any efforts to complete the meager information on emails would be appreciated.
Here is a link to a very good independent theoretical analysis of VMSK: http://people.qualcomm.com/karn/papers/vmsk.html [Changed to http://www.ka9q.net/vmsk/ - PRK]
The analysis in this paper looks very solid to me and makes sense to me. However, I am not an expert in information or communications theory so I am extremely interested in what anyone else has to say about this paper. I am also interested in peoples' evaluation of VMSK in general.
Classical electromagnetic phenomena and communication are well understood. Within the proper framework and with the efforts of qualified people, VMSK should be able to be well understood, precisely simulated, simply and accurately explained to layman, and associated claims definitively validated or invalidated. The confusion I think most everyone experienced at the meeting is totally unnecessary. It is the duty of AlphaCom, and if they do not do it, qualified professionals at the meeting and people like Phil Karn to do their best to uncover and simply convey the truth.
