Last time I did this dance, i2 was the all around best choice for a
Ruby wiki that was available.

Have things changed?

My priorities are in order:

0) Must run on TextDrive. (Most options should fit this one, right?)
1) Usability / Stability. Don't want it to blow up
2) Ease of install
3) Ability to make it look pretty
4) General l33tn355

This will be for the GoRuCo attendees wiki, incase anyone is wondering.
