How long until gigabit ethernet has all the kinks worked out of it? Let's
say second half of '99. You can probably buy a PC system with 1.6
Gigabytes/s of memory bandwidth and a gigabyte/sec going to graphics in
that timeframe. I still see an 8X performance hit on the network. ;)

How long until 3D Labs and E&S catch up? Assuming they haven't already.

Not without making sourcing the data from shared memory an API requirement.
Or dynamically checking on every API entry whether the data come from
mitshm. Bleh.
