AOLServer was the inspiration to the product I worked on, during my first experience working at a dotcom startup.
We had something similar, however it would plug into Apache and IIS, more configurable across several UNIXes and RDMS, and eventually even got an IDE coded in VB, for those folks not wanting to use the Emacs based tooling.
Eventually we also became a victim of the dotcom burst, however many of those ideas were the genesis of OutSytems platform, then rebooted on top of .NET, and still going strong on the market nowadays.
