They are offering live Firefox chat support now using an all volunteer support staff. They are just passionate Firefox users willing to lend a hand.
I had made this recommendation for a client back a few months ago to offer this in the venture capital and business planning industries.
Live chat support for any product or product line seems like a good solution that could be offered in many industries in a sort of open source kind of way.
Would take the right company to be open enough to partner with their "prosumers" or other heavy players that way. But definitely a cheap way to run a real clean, honest support program.
