Personal Servers And "Commercial" DSL?

Blue Dog Fever asks: "I've been helping a friend of mine look around for a DSL service provider. He doesn't need a lot of speed, but what he does need is the ability to place his own server on the DSL (in his case, it would be Web, e-mail, telnet, and maybe FTP). The only problem is, every DSL service provider we've looked at restricts the use of servers to their 'commercial' DSL offerings, which usually start at $120 a month and go up from there. What I'm wondering is if anybody knows of an ISP that lets people put up small servers for somebody that isn't interested in getting thousands of Web hits or huge amounts of e-mail traffic, but just wants to set up a small server for fun."
