Does anyone know of a good web hosting company that does streaming media?

I think any host can do it, it's no big deal. There is lots of cheap storage and bandwidth out there so unless you have a ton of traffic the cost shouldn't be too much. Phantomhosting.com has a deal now where you get 40 gigs of transfer for $30 a month. I've heard they were cool but I haven't used them. If you are paying much more than a buck a gig you are getting ripped off so shop around.
