Yes, I’m one of the ones who managed to somehow make it through Google’s mysterious vetting process, and after a 6+ week wait, have been invited to open a Voice account. I’ve had the account now for several more weeks, and am just starting to discover some of the more interesting uses.

First off, since I only have one actual real phone, the multi-ringing feature is lost on me. What I have been able to make good use of is the free texting and calls to Canada, and via Sprint’s conditional voice-mail forwarding I am now using Google Voice as my default voice-mailbox and handler.
For those of you who have no idea what this means, it’s like having Gmail for your voice messages. Recorded greetings/messages can be then embedded for sharing, etc.

Another fun thing is the call widget. Embedded widgets allow website viewers to connect to your account and to your phone; click, enter your number, and Google Voice rings both parties and connects the call. For free. Well, free in the US and Canada. Well, free inside the US and for US connections into Canada.

I’m going to try posting such a widget and do some experimenting; ideally, it should work out to be a “call me collect for free for everyone” button for my many Canadian friends.
