The Google Spreadsheets thing that I said something about a cpl posts up...
HTML output can look like this: http://taemun.googlepages.com/cb1.htm (it looked better before I saved and uploaded :S)
You can also output back to a xls file.

The editing screen looks something like: http://taemun.googlepages.com/cb.PNG

If anyone is interested in editing it with me, gimme a yell. (you can have "unlimited" numbers of concurrent editors :P)
