Digital Asset/Project Management Solutions for Mac OS X?

anwnn asks: "I'm looking for a complete digital asset and project management solution for my employer. My ideal solution would be something web-based, eliminating the cross-platform problem. I work in a Mac OS X based shop, with a few PCs sprinkled here and there. We need complete digital asset management, time tracking, project costing, expensing, and accounting. They're currently looking at a solution from Meta Communications, and my main problem with them is that they claim Mac OS X support, but in reality it's Mac OS, with Mac OS X support only via Classic. Ideally, I'd like to run something on the currently installed Mac OS X server, utilizing it's capabilities for Open Source solutions. What all is out there?"
