Hi Donnie,
There is a doc, from the NetTalk 4 days, in the docs folder, discussing deployment.
In addition to the information there I believe Rackspace is beta testing Windows VM machines as well.
I'm working on updating the NetTlak 4 docs to NetTalk 5 - but in the meantime the "share knowledge" section on his forum has interesting "mini docs".
Cheers
Bruce
