Interesting that you should mention that... I must have missed it as SIGGRAPH (I didn't spend enough time on the floor, I think). Any- way, I've been lurking on this list for a number of months (some of you may remember my inquiry about image change notification from Nov 99) with this very thing in mind. In fact, I have a plug-in to do this, more or less. It's very basic, but seems to work fairly well. Multiple people painting on the same spot can be troublesome, but that's fine by me. Since I haven't found a way for a plug-in to learn (by signal) when an image has changed, I did it the brute-force way: the plug-in main- tains an internal copy of the image, and periodically compares that to the one held by the GIMP. This comparison is done on a tile-by- tile basis. When a difference is found, the tile is distributed. /Emil
