My only concern would be the latency of your network. If you are using a 10mbps network or wireless, then you will not want to play larger roms (MAME CHDs, PSX, Dreamcast, Saturn, etc) as they could take several minutes to transfer. If you are using a gigabit setup, then you might be ok, but it depends on how you have the server set up. If it sleeps most of the time, you will have some lag between requesting a game and the transfer starting. There was at least one thread about a year ago discussing this. Perhaps you can find it with a search.
