Just a suggestion : Re-read my email...
I think only those may get cross posted emails who are members of more than one list. Now, why would one want to be member of more than one list? For the same reason one would want to post on more than one list. If there is something not specific to one region -- like national level why should other lists be deprived of it? If India goes for FOSS policy, where would one post it? iLUGD, Mumbia, Pune, Chennai? Or may to to as many as possible to keep everyone informed.
So, I guess cross-posting is OK.
