I've just tried distcc and the results are really awesome.
I'm sending a small patch which enhance the usabillity of distcc on my laptop where I use it at home and in the lab. The patch add code to check if a hostname can be resovlved before adding it to the hostlist.
With this patch, I can set all the name of the machine which I use, and, since the name of my home machine and the ones in the lab are not the same, only the locals hosts are added to the usable hosts list. Not exactly the autodetect solution, but it solve the problem in my case.
