Is it possible to use Apache Thrift on a regular web server?
Okay, well I have figured out the answer on my own!
If you use a TPhpStream on the server side, you are able to serve requests coming in as regular http requests.

I also blogged about how to implement a simple example with PHP and Python at http://willwarren.com/2012/01/24/creating-a-public-api-with-apache-thrift/
