Ted makes a good point here. You not only get the right to fiddle with the source, you get the responsibility to track down the problems that happen on your machines. The bugs may get fixed by other people -maybe- but without detailed diagnostics and stack traces, your problems will remain your problems, and not those of anyone else.
