hmm, from a user pointer of view it works like a charm, I really like it.
but as developer/packager...

no. that would require mapnik and postgis, which wouldn't work on an N810 I 
guess.

ok. we switched to sqlite, because it is very easy to install and use, and it 
is portable. I really don't want to go back to mysql again, though I don't 
know embedded mysql. maybe the sqlite people will fix this some day...

POI data is stored in sqlite.
the map data will be stored as bitmaps on N810; at least that is the current 
plan.

mapnik uses postgres with postgis extensions.
the live rendering is sometimes very slow on my car pc, which is 3-4 times 
faster than a N810, so I think this would not be usable.

data for routing will be stored separately, depending on the routing engine 
that is used. but that's a very new topic for gpsdrive...
