[Typo3] open feature ext. sponsoring

[Joe Frontman]

Hello,

in general, I would like to see a platform for extension donations, 
preferable on typo3.org
This should be handled like this:

- someone makes a request for an extension feature
- developer > defines a developing time frame and amount of money he 
needs for developing
- users can start sponsoring the extension
- everyone can see how much money has been sponsored and how much more 
money will be needed to start developing
- developer > starts developing the extension after the amount of the 
requested money has been sponsored

Please check out the "Donate o Meter" on the left side of this website, 
as an example: http://ravenphpscripts.com

What do you guys think about it?

Joe
