Try mixing Sun with an Appletalk to ethernet gateway and throw in a few PC's
Also, I don't have any idea what you 'hacked' into your realtime OS.  If
reasonable.  Or even better yet, try throwing in a network of Macs with
ethernet boards.

Also, I don't have any idea what you 'hacked' into your realtime OS.  If
ethernet performance was a high priority, then you obviously did some fudging
to bump up the performance.
