	Me, I have.

	I run a bunch of things from my home cable connection. I hate it, 
personally. This means that my stuff is on multiple blacklists 
PERMANENTLY.

	DPT systems, part of the north pittsburgh telco colo circuis, has 
some good deals on colo, I think. Colo is the way to go if you're hosting 
your own stuff. Otherwise, some of those el cheapo website hosts are gonna 
be your best bet.


> Is there a solution using a dynamic DNS service?

	No dynamic DNS, lest you control it. Comcast and other DSL 
providers generally won't do this for you, unless you pay tons of cash.

	Go drop a box off somewhere for $100/month. Best way to do it.
