b) how can we be online with 2 differents version of skype at the same time ?
quite simply -- you can be logged in from multiple places simultaneously, and there's nothing to limit what version of the client you use. i have even been simultaneously logged in with the same username on windows and linux.
What happen if you have skype 1.0 and skype 2.0 and the person starts a video chat ?
What does the IS_VIDEO_CAPABLE API returns then ?
The GET_VERSION API should probably work the same, IMO.
