I registered this app name originally and then transferred it to a Telerik account that Gabe gave me access to.
I'm not sure if they still have it reserved.
Lots of people are playing with getting 4.1 running on Azure, Brian mentions he has it running in this post.
It looks like the SF team are working towards a persistent config and maybe some interesting other changes to Azure compatibility in the next SP releases.
Let us know of your experiences. Gabe, are you planning an official Azure demo site?
