I'm under the impression that distributed builds are most useful when you have a high speed network connecting the computers. I'm not sure what it would be like doing it over the Internet. I'd be interested in hearing how feasible that is.


It sounds terrible to me. I once accidentally launched a distributed build with my laptop being only on wireless, the build speed was atrocious. I don't remember if that was 802.11b or 802.11g, but chances are your internet connection is much slower than that anyway.

Oh, and it just occurred to me that distributed builds only work with the same kind of processor, so you'd need to distribute to PowerPC Macs. You can't distribute from a PowerPC to an Intel or vice versa IIRC.

Not even that, but all computers must also have the exact same version of Mac OS X and Xcode.

It thought that might be the case, but I've never done DBs so I wasn't sure. I was just recalling stuff I'd read on the list a while back.


The upshot seems to be that doing a distributed build over the Internet from a PowerBook G4 doesn't sound very useful.
