is there a guide around which details setting up 1.5 and 2.x FB servers on the
same machine? I'm sure there's more to it than specifying different ports to
run on.

I've been using 1.5 for quite a while now and begun reading the release note for
2.1 (my how they have grown!). Scanning through the release notes, I didn't spy
anything...

A couple of week ago, I tried running 2.1 as an application (while running my
usual 1.5.x as a service), but couldn't seem to get it to start so I figured I
was doing something incorrect.

Thanks,
