Ditto, and my production servers are just a pair of Celeron 533 boxes!
 - just my business and the family to support, so perfectly adequate for
the job :) Since sending the email I've taken another look at their site
and there seems to be a very small number of tested motherboards, and
they seem to be from manufacturers like Tyan where you do wonder what
the benefit would be (bar ideological) since I believe this would
already be supported on many Tyan boards!

I've not tried at all yet, although again, since my post, I've taken a
look around and been quite interested in some USB to multiple serial
ports cables that I've seen. That would do me for now given the age of
my existing hardware - although since they do support USB as well I
guess USB to USB would be the longer term solution :)

Yes that's been on my todo list for a while, just never high enough to
actually do it. It is undoubtedly (in theory, ignoring unexpected
gotchas) fairly simple to do, but equally I've always found another way
around things (or been lucky enough to always have a spare monitor and
keyboard handy).
