Under 1E and 2E we did this all the time. The players would all have 2 or 3 PC's in play. It worked fine, but it is certainly true that the roleplaying suffers a bit under it, in the sense that a player has to divide attention. Usually one of the player's PC's becomes the 'front man' who does most of the talking, and one of the others pipes in here and there. As to the metagaming knowledge, we usually avoided that by not splitting the party along the lines of the PC's of different players. Since we adhered to rule 1 of succesful adventuring: never, ever split the party, as much as possible, this rarely turned into a problem. It definately helped with the mortality issue. A dead PC was never a showstopper.
