No I don't Jon...but you could experiement with the program and see if it will allow you to use Paltalk on one machine, while someone is one the second cpu doing something else on the Internet. I can't see how there'd be a problem if you were running Paltalk on the host machine with the direct modem connection. I can do most anything on the net, as well as play games or other non internet things while the other cpu in my office is being used by the kids visiting various cartoon and animated web sites. (Mind you I have a constant cable connection.) I think with 56K sharing, it will slow things down on the host machine, if the other cpu is on the web or whatever. Best to give it a shot, see how it works out, and if it does, great, and if it doesn't uninstall it.
