^Most wireless G routers support up to 32 wireless clients simultaneously. In theory, of course!!
@OP: I don’t know how reliable that list is, because I’ve used both a Linksys WRT54G and a Netgear WGR614 and never had any problems with torrents. Of course, I used uTorrent not Azureus.
The WRT54GL is just a plain router, not an ADSL modem + router. The WAG54G2 is an ADSL modem + wireless router and is a fairly stable unit. Have used it for sometime too, running heavy torrents without any problem.
