Google has never taken a hard line against Flash. In fact they've used it in a few Google products (Google Finance's charts are Flash for example). So I don't see why they wouldn't use Flash's superior media support for this.
I'm still waiting for Google Voice to be available to Canada.
I hate how long it takes to come to Europe!
It's probably taking Google Maps' suggested directions to swim across the Atlantic.
This is the first I've heard of a GV desktop app, and I really think it'd be great if they could make a good one and release it for free. But, is there any reason that they can't just integrate it with Google Talk and the existing software? You could just add a phone as a contact or something…
They don't necessarily need their own desktop app. Just enable SIP and allow us to use GV with existing VOIP software and handsets.
Yea, that would be useful, but I doubt they Google with partner up with people like Skype or anyone.
At the least, they should make an API available so that 3rd party desktop apps can be made.
