Full Fledged Web Based Software for services
 

I'm looking to find high quality ready-made web based software that's ready to roll out some kind of service... For example Mechbunny's Video software is advanced and ready to run back end for anyone with the content.

I'm looking for a list of any types of web-based-software, "Besides Tube Scripts. Cam Scripts etc"
in any category to use for ideas of things to do.

Thanks
