In a previous post I mentioned that I had an adaptor to run the Roundup Issue Tracker as a WSGI application. I never actually published the location of the code. So if you want to have a play, it can be found here. There are also 2 example ini files for using the adaptor with Paste.Deploy
Currently there is one unresolved issue: when using Roundup's internal authentication, after login the browser is not always re-directed correctly. This is not an issue for me as I use WSGI based authentication middleware.

As of Roundup 1.3, Richard Jones has added a wsgi handler so I suggest you use that one instead.
