Are we empowering people? Is everyone supposed to be able to access
this new world we are trying to create, or only the people with enough money to
afford the higher end equipment? I do use mosaic at 14.4. I expect to able to
use this new system at 14.4 also. I don't think that is a completely
unreasonable assumption. It does place large technical constraints upon the
design, but I think that if we design so that the lowest-end machine works
acceptably (5-10 frames per second say), then we know that all machines will
work well. This is also why I'm a little hesitant to support requiring a
CD-ROM, or any other "specialized" hardware.

Why don't we try to decide upon a minimum "usable" system? I think
that the browsers will probably take care of things like dithering and such, so
we don't have to specify 32-bit colour or something like that, but just
guidlines that might help in the design of VRML.
