According to the MindTouch website I was looking at, the "minimum requirements" are:
512 MB of RAM
Pentium 4 2GHZ processor
3 GB of Disk Space

But, I only have a team of about 12 people, working across the US on a single indie game, and don't have hefty requirements on things. Thus, I am running Debian Lenny on a 1.24GHz PPC with 512M of RAM (planning on upgrading to 1Gig) that I am using as an SVN server. I just need a simple Wiki my team can use for the project, and maybe I'll add-in more features/etc. down the road if they are available and we decide they would be nice to have. Will MindTouch work on my system?

Thanks!
