Actually the SHP part is setting the limit. DBF part can be much bigger and I
have myself one with 32 GB. See also http://trac.osgeo.org/gdal/ticket/3236

Spatialite has worked fine for me as a target when merging shapefiles but only 
up to about 8 GB file size. After that appending new data became too slow. It
was a long time ago and gdal Spatialite driver may be better now.
