I guess in that case your distributed build system would have a constraint that it always ships all the object files back to the primary machine (where you'd be running the debugger)? (perhaps it just always runs the link locally - even though it distributes the compilations - I guess that's probably how things like distcc work, where they only inject themselves into the compilation command, not the linking command maybe?)

Also, may require some work/more flags to handle the possible file renaming (or relative/absolute adjustment) when object files are built on a remote system in one location, but then moved back to the local system and placed in another location?
