I think any game that did this would have a "I didn't collide with
anything,I can walk through anything/anyone" hack.  This probably
varies greatly from game to game.  Personally, and I am not a game
development professional (so add as much salt as you like), if
you're willing to trust the client to do collision detection, with
it's limited knowledge of the true current position of mobiles and
ability to lie, then you don't care enough about collision detection
to bother, and might as well make things transparent (or add
'shoving past' text/graphics).
