Edwin, I maintain an installer which patches BI so it can run with EB. Most of the hard work is done in a .NET 2.0 dll which should be directly portable to Mono. There is also an NSIS installer script, which would need to be translated into whatever Mac uses an installer. There are very few files copied unpacked from the installer, as that would bloat it beyond belief. PM me if you're interested in knowing more about it.
