I tryed one of those a few years ago and it put the SU in ****...i think it`s still up in the closet someplace...
Seriously..the dirt cheap simple way is to get a cheapie TV card for your computer and use windows media encoder....you won`t have many "goodies" but it will let you play enough to decide if you want to step up to the next level
Here is the camstreams link to my fixed cam if you want to see how that setup works ( it can have audio too)....obviously check in the daytime as there isn`t much to see here at night.

That is a total investment of less than 100 bucks you can access it directly if you so desire without using a outside streaming server.
The other option, while slightly more expensive is to pick up a stand alone video web server, i`ve seen these in single channel form for slightly over 125 bucks...you can plug a convential camera into it and have at it.
