This is exactly the information I was looking for. Based on your response I
guess that my answer would be "not yet" so to speak. I will hold off on
trying this just yet, but I will watch Xen closely and wait with baited
breath for the day this might become possible. I have my doubts if it will
come to fruition though. Now that Cirtix is involved, my goal is quite a way
off from the Citrix push. Their website seems very geared towards server
consolidation and thin client services; as would be expected, that is were
the money is going to be.

I don't know how much the open source end of things are steered by the
commercial side, but the situation I describe really would be the Holy
Grail. I see it as a way to prove this platform for VM as the undisputed
champion, and a way to rise above VMWare. If that were to happen the
commercial values would certainly follow.

I will stay registered to the list for a while, as I imagine that I can
learn quite a lot here - even if I am not ready to jump into the product
quite yet.

Thank you Jim. As stated earlier I will report this back to the other forum.
