Honestly, it wouldn't take you long to get the skills if you could get access and were a decent programmer already. One of the problems with these sorts of systems though is that it's not like they're open source and easily available outside of the enterprise.

Want to set up a testing instance and just play around or build something? They're either not available or horribly crippled. If you can get into a company that is doing it already and you can get access, you will have an easy time learning it (but it's not exactly fun).
