The other big thing I'd like is to automatically check versions, making
sure that jobs are only sent to machines which have a matching gcc and
binutils (as gregkh just discovered).

I love Python too; I would be happy to ship supporting programs written
in it. But ideally this should be built right into distcc, and
therefore probably in C.
I wonder if it would be feasible to automatically discover the machines
speeds. It would be OK if there were an OS-dependent bit that looked in
/proc or similar.
I don't think this would be mere mechanical porting; students could do
new development using Victor's code as a prototype.
