Does this mean interactive decision layer by layer, or that the module 
should allow for entering layer and type as an option ?

It will have to be something like:

for map in `g.mlist type=vect pattern=$GIS_OPT_PATTERN
   do
    v.out.ogr $map type=$GIS_OPT_TYPE layer=$GIS_OPT_LAYER
   done

where GIS_OPT_PATTERN would be something like 'nome_vector*'

If you need to automatically decide which layers and types to export, 
you might be able to do some grep/awk magic with v.category -g $map 
option=report.
