FOSS is free as in puppy.
In a paper released in 2004 CSC recommended organizations maintain a "sweet list" of useful open source applications and make them available for people to tinker with.

Since FOSS is peer to peer software. A formal training program is not a good fit. (The word train means to drag behind). What is needed are instigators, faciliatators and encouragers. Someone who has found the value for him/herself and has learned how to navigate the landscape of FOSS.
I like Chris's comment
"I think that the open source revolution is a lot like the teaching/learning revolution. We all need to learn to depend more on each other, rather than a paid support solution. "
Yes there is alot of FOSS software. Not all of it is wonderful. There is also plenty of paid and proprietary software that provides good value.
The trick is finding the value in what is out there and making those tools available to your group. It is the role of the teacher (or the tech enabler) to communicate the value of the tool and more importantly how it can be used by someone who needs to solve a problem or do something more efficiently.
