The final version of Skype 5.0 for OS X is now available, with group video calling, and a whole new interface that Skype says has been “slimmed down” and allows you to see 30 percent more contacts at once……See Details.

The Group video calling feature is now apart of the premium package which, after a free seven-day trial, will run you $4.99 for a day pass or $8.99 a month for a subscription (though you can get 33 percent off if you sign up before February 28th).
