I haven't had problems reprojecting sizable datasets (e.g. 4800x1600 cells 
latlong to 4000x3000 cells albers equal area) on a RedHat 7.0 box with 128 
mb RAM and PentiumPro 200mhz. It's slow, and this is not the machine I 
would work on by choice, but it doesn't choke.

Two thoughts: If r.proj is choking due to a lack of memory, with the price 
of memory chips these days, I don't think it should be hard to justify 
bumping up your RAM.

Alternatively, I wonder if there are some factors that influence success 
with r.proj besides available memory (e.g. could be that different source 
and destination projections require different resources).
