Advertising dollars to support local enterprises?

I'm afraid I'm cross posting a bit here, from the Trust System board and the seeds & gardens thread Zet started. In various places it has been suggested that the 'seeds' be integrated into a system that supported charities or local ( zaadz/gaia developed?) enterprises. 

The idea being that some revenue from sponsors be put towards zaadz/gaia chosen (or grown?) enterprises. The seeds could be how we as a community decide what enterprise at any given time be allocated the money. Here are some of the relevant bits from the above thread:

Zet: Zaadz needs to grow economically, and however weird this sounds, this should be in our interest.

DavidC: Yes,
yes! Your suggestion that Zaadz offers advertisers a way of 'giving
back' is a great way to get seeds to work in the real world. So
advertiser dollars goes to Zaadz/Gaia community project for example and
Zaadsters give seeds to the idea they'd like to grow. This would be a
direct way that we, the Zaadz community ,could manifest our vision into
the larger community of the world.

Sandra: I  believe that one of Gaia's long term wishes is to support local enterprises - how wonderful if these were Gaia community inspired 'enterprises' or projects …. (which, of course, align with the 'mission' of Gaia - re changing the world).

eg
- - (once running costs be covered etc) - every month (or..) an
advertiser's money goes towards funding a Gaia community inspired
project – and we as community members not only put forward our
'projects'/('gardens') for such funding, but we as a community use our seeds to say which 'garden'  (project/enterprise) we would like to see grow at
any given time. Perhaps this is where 'weight' comes in –  a person
whose seeds 'weigh' more, their seeds count for more in the 'seeding
which garden project' decision.
