The way I see it, providing the shells is relatively easy, but keeping

your line free of DDoS and other niceties it brings is not worth the

effort, especially if your users use IRC and bitch about every second of

downtime. Suddenly $10 isn't so much, and it's a lot more than the cheap

shell providers cost. Without good relations with your ISP it's not

going to be easy to keep your connection at all when the users get

nasty.
