You should search the list archives for recent posts on distributed builds,
say, the last 3 months.
Xcode makes some distributed-build decisions that go against seemingly
obvious performance factors.
For example, a distributed build started from a powerful machine (e.g. Mac
Pro) will distribute compilations to puny machines (e.g. iMac or Mini) on
the network, but will not do any compilations itself. Instead, it
apparently exempts itself from assisting because it's doing the
preprocessing and other phases itself, even though a Mac Pro by itself is
twice as fast as any puny machine.
In short, adding a Mini for distributed builds may gain nothing in net
build speed. Distributed builds may end up slower than your MacBook-only
builds are right now.
The Mini makes a dandy lightweight file server, though. I use mine for
that, in addition to other tasks (but not distributed builds).
