I recommend to test your feed scripts on the testnet first .. not that you cause a blackswan or something similar by accident

you don't need to ask witnesses ... you can have any account publish a feed ..
http://docs.bitshares.eu/bitshares/tutorials/mpa-create-manual.html
there are too flags:
-                    "witness_fed_asset" : True,
-                   "committee_fed_asset" : False,
If both are false, you can select your own producers by  update_asset_feed_producers
you could even change this on the fly if you set the correct permissions

You need the active key of the issuer of SMART imported in the same wallet!

It may be (not sure) that the cli-wallet requires the owner key, but it shouldn't according to the protocol

// edit: :P

:) Do we have to convince a witness to run a feed for this, or can we run one?

edit: many thanks for your help by the value, it was invaluable :)
