I only use their hobbyist program, I'm afraid.   (Which is much appreciated)

I'm not complaining about the product, and I don't wish my previous
note to be misconstrued as a complaint about the product itself.

The TCPWare product itself seems quite good, just the SSH encryption
was really slow.   Host key generation, (measured in 10s of minutes)
as well as session key generation (measured in minutes) were slow.
The per-session key generation was slow enough, in my case, to make it
unusable.

I'm sure relatively slow Xeon's + Vmware + Fedora 11 + SIMH + SIMH CPU
Throttling, was a significant source of much slowness.....
