new skype is out on Mac - very nice features have finally made it in there - they help balance the ichat vs. skype conversation pretty well, mainly:

- the usual pushes to improve sound / video

- screen sharing (very practical with parents :P - don't think it includes controlling the other screen - just seeing)

- a skype credit based wifi feature which let's you connect to existing wifi networks; <-- this can be very interesting if the access points to cost ratio is high

Oh, and if you're in Canada, Skype has been out is finally downloadable in the app store

Oof - that was a mouthful of Skype propaganda - but they've been doing great with their software, and I want to see it improve.

Cheers!
