I'm trying to write my midterm paper this weekend.
the abstract is at http://www.sims.berkeley.edu/~katster/classwork/is204/abstract.php.
the paper assignment is at http://www.sims.berkeley.edu/academics/courses/is204/f02/midterm_paper.htm.
If you've used the systems I've mentioned there or can think of another system along those same lines, or can think of anything that would be helpful to me, *please* comment here or track me down on IRC, if you're the sort to do that. If you help, I'll include a credit in my paper, and I might even end up citing you... :)
