Hi,
I skipped quite abruptly from 0.12 (?) to 1.2cvs because I used to have 
a TCP load-balancer to distribute the load UNevenly. AFAIK, the 
scheduler works perfectly -- on my medium-sized project (>300 C/C++ 
source files) and small 100M LAN segment (3 machines). Setup is now 
simpler, and I measured some speed gains (about 10-15%).

I'm a bit new to distcc -- I mainly use it in a small lab environment 
with few (3-5) machines with very different perfs. Couldn't distcc sort 
of balance the load depending on how fast the machines are?
I currently use a simple equation, max tasks = cpus * 2 (as suggested 
in the documentation), but I'm not sure if this is the best solution, 
and it certainly isn't scalable...

Anyways, distcc rules,
Cheers,
