Random ideas: 1. You already have a 'save' button: ctrl-S .. It should not be hard to get the drawees to hit a key shortcut now and then. 1.5 *maybe* there's some way to get inkscape to save on a timer -- perhaps a python extension. 2. Poll the svg file (save it someplace predictable) with some kind of loop. Perhaps do a diff. 3. Send the xml (svg) off to your server. If it's a diff, do some kind of patch on-the-fly. 4. Give each performer/drawee a layer of their own -- that way you can live-mix what they are doing. 5. You could even use lxml (or whatever) to pull the data apart and re-combine it into an output (so you can control which layer is on top, scale and so on) and then use pycairo to produce a live PNG output, which your html/javascript can then pull at intervals. (Not sure about browser support for svg yet, so maybe a png/jpg will be best.)
