various architectures will get built and bootstrapped in various places,
splitting these up to feed build, ci, test, community access etc just
dilutes the capacity massively.

i dont think build location and repo location are the same problem

We've run geo distributed builders since CentOS-4 days, and havent had
any major issues so far :) I am sure we can maximise the impact of
smaller more focused machine donations to the project going forward in
this way as well.
