Could these tutorials be actual MPEG movies showing screen captures of
what was done?   I've seen such kinds of tutorials put out by different
companies (e.g., ESRI), but I don't know how difficult it would be to do
or whether the resulting MPEG would be unmanageably large etc. 

My 2 cents.

if there is interest on this topic, i could prepare some tutorials out
of my presentations (fossgis in bonn, foss4g in lausanne). though i got
some positive feedback, i was never shure, if the presentations are good
start for such kind of tutorials.

when should next release of grass news come out?
