I my case I'm pretty much only really interested in direct point to point communications.
If you are relaying your radio stuff through the internet then why bother?
Sure just because you can is great, but if you have to do that, might as well just use the internet and skip all the FCC regulation BS on what you can and can't say and such. You might as well use one of the really cool internet voice chat room programs.
I could only see it being useful for edge cases where folks without point to point communication ability want to talk to someone that can only do radio and has no other internet access and such odd cases like that.
Repeaters are fun and all, but then you are relying on somebody else's equipment to be up and running and powered.
