You might want to take a look at the wildfire modeling routines already in GRASS. I think that with minimal work, these could be modified to become general spread-modeling routines. I've used these (with some difficulty) to model the spread of other phenomena than wildfires and would love to have general spread routines in GRASS. > > It sounds very well suited for Linux or MacOSX, but I've little idea about the > GRASS+R Windows situation.

It is a powerful and (relatively) easy to learn language that will become increasingly important to GRASS in the future. Extensions scipy and numpy give it additional abilities.
