Hi Brenton,

I'm just waiting for a frind to finish some tests with a SSL accel. card
from VIA. The prices are very expensive for average users, but it's a
market with high demand and we expect better prices in few months. I'll be
glad to let you know the model and compatibility X performance results
when these tests are done.

Keep in touch,
