Hi,

FWIW I've been doing something very similar in grass for a number of
years. see v.surf.icw from wiki addons. it has suited my needs well,
but with the newly much faster r.cost module it becomes a lot more
viable for general use.

their approach seems to do in memory what I was doing with temp files.
(suggest mapset on ramdisk to reduce disk IO bottleneck)


regards,
Hamish
