You're a very patient person, or your offline machine is at least
a 4 3Ghz Xeon with 4 GB RAM, or you never compiled something like
X and/or OpenOffice  and some other nice little things ;-) .
It is that what you're describing is a lucky, but I fear uncommon, 
situation: you can afford a plus machine and you don't have different 
machines and machines types to compile for. I think that a common 
situation, with different machines and machine types and production 
machines, require a big overhead either in CPU load, either to schedule, 
monitor and manage the compilations for not suffering for such CPU load 
increase.
I made what you're describing, but also in my case, with the same 
machines and machine types and the CPU load increase was not a concern.
I think that in most cases, with a smart monitoring, scheduling and 
managing and with ccache and distcc you can get the target also in more 
common situations without performance degradation in the business 
services offered by the machines, but there are concerns either for 
security (gcc installed everywhere to have distcc working) and the work 
for managing monitoring, scheduling and control the CPU load and network 
traffic increase.

Sorry for the beastly English, but I can write a worst French and also a 
very bad Italian ;-)
