Watch out - Skype on a smartphone is power hungry, because the processing and encoding is done on the handset. There is a rival technology called "Fring" - which sends your phone/video call to the Fring servers for encoding - so your battery will last longer.
Also, Skype's VOIP encoding on a smartphone uses propriety encoding - Fring does not.
If you have a spartphone then download Fring
and give it a try - it's free - and you already have all the equipment you need!
