I want to develop a tool for my project using python. The requirements are:

Embed a web server to let the user get some static files, but the traffic is not very high.
User can configure the tool using http, I don't want a GUI page, I just need a RPC  interface, like XML-RPC? or others?
Besides the web server, the tool need some background job to do, so these jobs need to be done with the web server.

So, Which python web server is best choice?  I am looking at CherryPy, If you have other recommendation, please write it here.
Use the WSGI Reference Implementation wsgiref already provided with Python
Use REST protocols with JSON (not XML-RPC).  It's simpler and faster than XML.
Background jobs are started with subprocess.
Python web server?
