Well, v6 and v7 is sort of long-obsolete (it was only used for 
direct export from cat5000 line cards, if I remember right, and
never used anywhere else).  

v8 is netflow aggregation, and this can be done with the v9 format as
well, so no need for yet another export engine in the routers.

(Never seen v2..v4 anywhere, must have been lab versions)
