In a nutshell: you switch when you need a different toolchain, and you need a 
different toolchain for different targets (unix, xen, kfreebsd, ns3, 
javascript).  Each toolchain will have platform-specific hacks and restrictions 
that may render it unable to target other binaries.

Now that I've got OASIS working, I'm going to ripple up the changes through to 
mirage-www, and then we can get the blog updatable again. The joys of 
self-hosting ;-)
