If you are able to provide a few dedicated machines for the GCC compile
farm (let's say 2 or 3), and also provide support for them (updating the
OS, installing new packages, etc), then this is really a great addition to
the farm!

Regarding practical matters:

- we need direct SSH access to the machines.  It can be on ports different
  than 22, so you can use the same public IP address for all machines.

- we deploy users and their SSH keys using Ansible (via SSH as root).
  I expect it will work well on Solaris, but if you provide a first
  machine we can test it.

- we also use Ansible to automatically gather technical information, for
  displaying them on https://cfarm.tetaneutral.net/machines/list/
  We also install packages through Ansible as much as possible, so that
  new machines automatically get all the packages previously requested by
  farm users.

- regarding storage, we need ideally at least 500 GB for /home on each
  machine: users tend to leave stuff behind.  If it's too difficult to do,
  you can put all storage for /home on a single machine, and mount it
  through NFS on all other machines.

Does that all sound good to you?
