I know quite a few people here are using Linux as file servers and desktops, so I thought I'd ask here.

I'm looking around for project management software that is either web-based (and high end) or client-side and has a client for both Linux and Windows.

Anyone know of any? This is driving me up the wall. The PM on one of my contracts and I are having a hard time keeping organized. He's running a linux machine as well, but his empoyees aren't.
