> There needs to be community pressure on companies to allocate resources and time for employees to contribute back to whatever projects they use.

Companies don't allocate resources and time to employees without expecting a return on investment. Any contributions made on company time would have to managed by the company with the intent that they serve its needs first and foremost, or else be considered theft of company resources and time.

It sounds like a good idea but I can't see it turning into anything but an opportunity for companies to leverage control over open source projects.
