Can I use GV to text abroad if the other person doesn't have GV?

The other person is in Canada and has a Blackberry -- anyone know of another app I can use blackberry>android and vice versa?

For text messaging? The OS of the other device shouldn't matter. Are you asking about instant messaging?

Don't know about GV, but i use PingChat. It's available for android/iphone/blackberry. I used it when i was in south america to chat with family back home in the US. It works on 3G or wifi. Both of you have to install it on your phones.

check to see if your canadian friend has Google talk on their BB

Not sure how sms works internationally (rates and such), but all of the IM apps should work (google talk, aim, ym, msn, pingchat)

Pingchat will work like BBM with the confirmations. LiveProfile doesn't have the BlackBerry version out yet, but it should be available soon. Most should also work via 3G or wifi.
