[IPT] Access IPT via web services

Hi IPTers,

I'm looking for a way to access an IPT instance as a web service. What I would like to do is poll for a list of the available resources in some machine friendly form, such as JSON or XML and use it to decide whether there have been any changes that I am interested in.

I think that I can probably do it via playing around with the the RSS feed but I would like to see if there is a more direct route that I could take or an extension that someone has already developed.
