Hey ,
I'm also pretty active in the Asterisk world and there we have a bounty system.
If somebody would like a specific feature implemented, it will be posted in the wiki (because there is no forum). Then if somebody wants to take on the development, they can start it and if they feel they have fulfilled the requirements, they submit the project to the person who is offering the bounty.
If it is a feature that many people want, quite often more people are adding to the bounty and then each person decides individually if the result fits their ideas and if they want to pay the bounty.
Here you can have a look at the asterisk bounty page: http://www.voip-info.org/wiki/view/Asterisk+bounty
Has there ever been something like this for FG? I think, it's a very good idea because that can really motivate people to take on development.
Are there any reasons that would stand against bounties for FG development?
