I know you guys mentioned that an outside company was working on the Mac port, any news on its status?

Also, just an idea: You guys should add a Donations section to your site. I know I for one got the game rather cheap on Steam, and would be more than happy to help with additional funding for your future projects. Defense Grid has given me way more than $10 or $20 worth of enjoyment, and I'm sure you're fans would love the opportunity to tip the scale back in your favor.
