A heterogeneous network presents a lot of challenges, but few are insurmountable, especially if you get some good advice.

Check out the TechX World roadshow - you'll undoubtedly gain some valuable insight. There will be tracks covering the challenges I mentioned, plus there will be tracks on virtualization.
