Wi-Fi Video Conferencing My daughter will be in Japan soon, studying abroad. And she just got a Macbook Air. Meanwhile, I have Android 2.2 and a Samsung Galaxy Tab. I don't mind paying for an app, but am not too keen on monthly service bills. I want to be able to have video conferencing with her on Wi-Fi only. I imagine SIP would be the way to go.

So what is the best app out there for Android right now for doing Wi-Fi video conferencing between a Mac and a Samsung Galaxy Tab, and which lets me do unlimited calling, not charged by the minute? I don't mind paying even up to $50 for the app on each system, just to not have to pay the monthly fees. I looked at the Tango app, but it said it only installed on iPhone and Android. I didn't see a Mac or PC version for it.
Another option will be ooVoo.

The free version allows 2-way video chat between Android and Mac (plus many other platforms)

They are expected to release a version for the Galaxy Tab in February according to this http://www.cnet.com/8301-19736_1-20025684-251.html
