Yes.

Nothing really fancy. The RPM Fusion mirrormanager instance has a local
mirror and I think it is necessary.

The RPM Fusion mirrormanager uses postgresql and I am pretty sure also
the Fedora instance uses postgresql.

That is possible. If you look at mirrors.rpmfusion.org or
mirrors.fedoraproject.org you will see that both resolve to at least two
machines. You can have as many as you want. The mirrorlist for RPM
Fusion is running on two VMs with CentOS 5 (32bit). One with 512MB and
the other with 1024MB. 512MB is sometimes not enough so I would say at
least 768MB. The mirrorlist for Fedora and RPM Fusion are not running on
a live copy of the MirrorManager database. They are refreshed hourly.

As far as I know most of the Fedora setup is running on RHEL 6.
