conserver can interact via ssh by invoking the ssh command as it's
method of talking to the console (instead of creating a direct tcp
connection on a port - normally 23).  in this case, whatever the ssh
command does determines the traffic (so, port 22 by default).

yep, there's a conserver/convert program that gets built that you can
point at your conserver.cf file.  the conserver.passwd file is a little
more straighforward and left to you.  look for references to 'convert'
in the INSTALL file for more details/instructions.

there's also a conserver.cf/samples directory with random examples of
things i pulled out of my head.  those could definately come in handy.

i don't have any strong feelings, but i can tell you that i was
developing conserver under fedora core (2, at the time) and currently
have 3 installed - but haven't done anything with it.  all my real
development work has been under solaris.  personally, i'd go with fedora
core over ES4, but that's 'cause i'm cheap.  ;-)  and i like the
features of the latest code, as opposed to the "stable" (ehmmm) system.

but, honestly, any system should be fine. just realize you'll have a
handful of conserver processes and then N ssh commands (wrapped in a
shell), so memory use (and possibly some cpu crunching depending on ssh
overhead) will be things to watch out for.
