This is great. I am looking froward to it.
To gain understanding, I have installed it on a standalone machine. The default installation gives the bare features one needs to make basic visio conferences. That would already be great to have just that into the app store.
Though advanced features, like recording conferences or desktop sharing will require additional pieces of infrastructure. Though, these additional efforts will be well worth it.
Let me know if I can help you in any way regarding this matter.
Cheers!
