And that is the problem I think. Try just to take original code and 
remove BEGIN and COMMIT from V1_write_line_post (write_post.c),
insert BEGIN to V1_open_new_post (open_post.c) and
insert COMMIT to V1_close_post (close_post.c).

Yes, but it works only for points and lines and a view must be created
to get everything (geometry + attributes) in one table. 
Any Web GIS application (MapServer) is usually a lot of work and 
it is using limited number of layers, to do v.out.ogr for those 
few layres is not problem, vector data are not big. 
It is bigger problem for rasters, which are huge and cannot be effectively 
shared by GRASS and Mapserver. I am not sure if using PROCESSING "BANDS=1,2,3"
and grasslib can solve this partialy.
