[Mono-osx] MonoMac / Build process and obfuscation

It's not pretty; however I found a solution that works for my projects.
First, I build all of my dependent projects like normal.
Second, In my target MonoMac project I have a script the runs "before build" which obfuscates all of the dependent libraries. It does this by starting a virtual machine (or making sure that it's running) on the same mac that is doing the build, and then SSHing into that virtual machine and calling a batch file that obfuscates the assemblies. The virtual machine is configured with a "shared directory" that points to my actual project in the Mac file system, so the obfuscations are done in place.
Since the obfuscation is done before the MonoMac project is built itself, the app is built and signed with the obfuscated assemblies.
The only limitation to my approach is that the MonoMac project itself can't be obfuscated since the script runs "before build"; however I worked around that by moving everything I want obfuscated into a dependent project. My target MonoMac project pretty much only consists of resources, property lists and enough code to bootstrap the app.
