Install with the same CDkey?
Create a new character with the same name, the database recognizes by serial so it doesn't matter where you go or which computer you use, as long as the character name matches with the key you have for warband.

Characters inside Warband have nothing to do with your actual cRPG character.
Only the name and your cdkey is important so the correct data can be received from the cRPG database.
There is a profile file in X:\Users\YourUserName\AppData\Roaming\Mount&Blade Warband\ (should be true for Vista and Win7 not exactly sure about the rest).
I am not sure it is compatible and can just be copied over but that one would include your character profiles inside Warband in case you want to keep your faces.
