We've been using Unfuddle for a while and have been pretty happy with it, although we always felt that the built-in RSS feeds didn't have enough information. Recently they released an API, and so we decided to make a new Unfuddle Project RSS feed, using PHP, that displayed richer information like times, people, and comments.

To install, edit the settings near the top of the PHP page to use your domain name, login, project id, etc, then load onto a friendly local PHP server. It requires PHP 5 due to use of the SimpleXML extension.

One thing to note -- the file doesn't contain any caching mechanism because different PHP hosts have different things available. So feel free to add in caching support, or lmk & I'll upload a version with caching included.
