I am wondering the same thing; the Xen versions shouldn't be *that* different,
should they...?

The Xen versions are not *that* different as they can run the same domU without any problem. The original question concerned the ability to live migrate a domU from one xen version to another one on the same hardware. The answer is a priori no, and it is not surprising : as I know, no other product is able to do that (I don't think VMWare does it). But as Xen is the greatest, I hoped it can do that.
