I am subscribed to the list as of a few weeks ago.

Would it be feasible to use the same machines for that?

Regarding scheduling, I think we'll need a *lot* more nodes to get real
archive coverage, or maybe selectively schedule packages for builds that are
known or suspected to have architecture-specific divergence (e.g. builds
different packages on different architectures).

Network isn't amazingly fast, but there's a squid-deb-proxy on the local
network for package caching with ~40GB for the cache, and it could be
expanded if needed.

Will give you access and free reign to set up as you wish. :)
