It's not like this is JavaScript specific.. Any project that wants to be cross-platform has this issue. That's why there are also already solutions, for example buildbot. You can get it to check for new revisions in your VCS and run it on any platform. This is happening all over the world, using different systems (OS X, Windows, Linux, *BSD) with different versions of the OS and different compilers (GCC 4.2 GCC 3.4, Visual C++ etc). Yes, if you want to be compatible, you'll have to do a little effort, but Javascript suites are hardly the first to figure this out. Everybody is doing it with relatively few issues.
