I think it would be fine to give Colin a VM on clutter and see what
happens with this. In terms of resource utilization:

 Disk space: not a concern - we have lots more disk space there than we
    can reasonably back up (we have about 1.5TB free unallocated right
    now)

 CPU - generally not a limiting factors for the services we're hosting.
    Say limit to 2/8 cores on the machine.

 Memory - I think we're fine allocating 4GB/32GB for the machine.
    (More if that would reduce IO bandwidth)

 Networking bandwidth - if thousands of people start updating, we need
    to start measuring but initial demands shouldn't be big.

 I/O Bandwidth - the resource where we're most constrained. Right
    now we have basically no I/O on clutter (which has a pretty good
    raid array). The only thing it hosts is extensions.gnome.org which
    is database backed.
   
    Migrating mail/etc. onto this machine might make us more
    constrained, but I don't think it's a blocker.
