Ah -- I see what you mean by cumbersome now.

That would be nice -- anyone know? I suppose looking at the 
gdal_rasterize code might help you figure it out.

Another option is to rasterize to an in-memory bitmap  with another lib, 
like PIL or pyCairo, or mapnik, or maybe mapserver, though I don't know 
if you could keep it in memory with mapserver.

I"m glad that worked out.
