Do you really want more than 256 people on one box simultaneously? Using a terminal server front end will allow you to switch users based on incoming protocol type, load, or software version. (you also don't have to futz with serial drivers or burden your box with serial interrupts). I use Xylogics Annex-3's for our incoming dialups. Based on the account name I can switch the user to an older sysv uucp box, one of two newer FreeBSD boxes, an NT box, or PPP directly to our Cisco/T1. One philosophy of design that you definetly do not want to use is the "one giant box does it all" plan. This is an old mainframe plan and every plan has a flaw! In the 80's the centralized versus distributed debate was fought and the centralized guys lost. Regards, Mark Hittinger bugs@win.net
