UML sequnce diagrams can be pretty useful to show these things. Especialy if you have asyncronus events, or multiple threads or processes, which ordinary flow charts dont model very well. PDF on sequnce diagrams.
Apples iChat lets you chat in a P2P manner with redezvous. You can open up a list of 'near by' people as well as your buddy list. They have made redezvous an open standard, so it could be used by open source systems too, although I know of no opensource implimentation yet.
The way the do this isn't new. Despite the quite poor explaination of how it works in the review and on their home page I think this is a minor variation on the parral barrier method, explained with diagrams here (N.B. the first method on the page). All they have done is move the barrier from in front to between the liquid crystal and the backlight. It was invented by Frederick Ives in 1903, so it's not that new. If you want to make your own you should try printing a lot of fine lines on some acatate, and experimenting with that, certainly cheaper than their monitor.
