Clean them off. I'm sure dicko will find a way to work things out- either separate sessions, as you say, an option to start your characters at a higher level to offset the EXP gain (Leaked Experience), or whatever. So I'm sure it'll be fine.
TO Digress.. . . I like some of the new 4e concepts, types, and areas- the Genasi, the Primordials, and Returned Abeir spring to mind- but haven't actually played in the battle system. I suspect some of the new characters could be converted to to the old versions, so one could play a Genasi in 3.5, for example, though origins might need some altering, unless one decided to use the 3.5 rules in the 4E world.
