The code was pretty straightforward, really. Some stuff had to be hacked up here and there, but it works.
As you can tell by the windows being drawn, the left picture was taken on Windows XP and the one on the right is on Linux.

Naturally, there will be problems with data replication and synchronization here if multiple people try to set a value to a cell (be it the same one or a different one), but whatever.
