The "slow windows on a desktop" of grass roots VTF has some major advantages:
1. Testing: FAXes and phones provides a way to test the premises of visual telefacilitation right now, without waiting for expensive hardware or software to be developed.
2. Deployment: FAXes and phones insures the immediate deliverability of more effective teleconferencing to the greatest number of people. This grass roots availability of visual telefacilitation is very important. Groups with access to paper FAXes and telephones number in the hundreds of millions; groups with access to all other teleconferencing media combined number only in the low millions at best.
3. Benchmarking: FAXes and phones will provide a very cost-effective reference point against which to measure the more sophisticated and expensive equipment systems.
4. Upward Compatability: FAXes and phones, when
implemented using FAX modems and FAX software on PC's,
utilizes FAX as a grass roots computer graphics interchange
