It may appear that the VTF project has a low tech bias, but this is simply not the case. We at PGC like fancy technology as much as anybody, if not more so. Visual Telefacilitation using real-time shared text-graphic media over the Internet to support full duplex video teleconferences. Yes, that would be really neat [see PGC prototype in figure 8].

But is "really neat" enough? To some extent the burden of proof is on the exotic equipment. For the near future, FAXes and phones, or perhaps the Web and phones, may well provide the most cost-effective telemeeting support.
The VTF project does not have a low tech bias; it has a best teleconferencing to the most people at the lowest cost bias.
