It has been hard to get invites to the service so far, but if you are a student, you get one within 24 hours.
Head over to google.com/voice/students and enter an email address that that ends in .edu, and you get the invite within 24 hours. (I tried it, it works)
The service is only available in the U.S., and I recommend that if you get it, and own an Android phone, get the free app from the market, it makes the service a lot more handy.
You can check out all the videos on the service here: youtube.com/googlevoice
