On a quick note, I noticed that the last script mentioned has a link on their website to
http://www.jaguarpc.com. It says that they'll install all of the modules needed for the site to work if you buy videoshare from altrasoft and host at jaguarpc. Jaguarpc has decent rates for hosting so that's not a bad deal...although I still wonder how much bandwidth is ample. I guess as you grow you should be making more profit (hopefully) and could upgrade if the time comes...
