Yup - keeping the slaves running is the big problem.

We do have various slaves running here that at least are all
accessible by me, and Jarrod, and (at a pinch) Fernando, Stefan and
others.

These are:

XP (when I'm not using the machine, which is the large majority of the time)
OSX 10.5
OSX 10.4 PPC
Linux 32 bit
Linux 64 bit

These are all real machines not virtual machines.  I'm happy to give
some reliable person ssh access to the buildslave user on these
machines.  They won't necessarily be available for all time, they are
dotted around campus doing various jobs like being gateways, project
machines, occasional desktops.

See you,

Matthew
