There are several other options available to you (well, there were
before too!) but... the piranha packages are available for Centos5,
which is essentially the same as RHEL5 and in turn similar to Fedora 8.
You could do worse than download them and try them out.

Now I do have to ask why you'd create a single real server, regardless
of power - if it goes off for whatever reason (power, patching,
overload), you're hamstrung.

Well, you could just continue with what you're already familiar with if
the Centos RPMs work. If they don't, grab the SRPM and compile that.
If that doesn't work there's:
ldirectord
keepalived
heartbeat/mon
They all do similar jobs in different ways. I guess the best thing to do
is try them, see what you think, and find the one that works for you.
Ask back here again for more specific help :)
