Being interested in this technology I did some web research several years ago and this is what I remember as best I can. (You can do the research yourself today to see this)
In approximately the year 2002, Sorenson demo'ed a videophone prototype at one of the technical expos which later became the VP-100
Jon Hodson (In People magazine around the year 2003 I think) suggested to his wife's brother (Jim Sorenson) the idea of using Sorenson's prototype for VRS purposes for deaf/hard of hearing and the VP-100 came out of this partnership.
Sorenson Media, the company that developed Squeeze (which split from Sorenson Communications later) developed the VRS software for the VP-100 and DLink built the VP-100 hardware for Sorenson.
DLink liked the idea of a videophone for hearing people to use and Sorenson licensed this videophone product to DLink for DLink to sell as the i2Eye DVC-1000 videophone (The silver one that CSDVRS and others started buying and distributing to deaf users to use their VRS services)
Sorenson also developed and licensed the i2Eye software for DLink's DVC-1000 videophone for resale to the hearing public.
I haven't seen a VP-200 i2Eye version developed/licensed to DLink for resale to hearing people and this is probably because of what happened with other VRS companies buying/distributing the i2Eye DVC-1000 videophone to deaf users.
