[Ambassadors] cost/benefit of switching to open source

[Matthew Cascio]

Hello Ambassadors,

I'm working on a strategy presentation to help a client understand the 
cost/benefit to IT departments for switching 100% to open source.  I 
searched the list archives, but didn't see anything relevant.

Can anyone point to some good research on the topic or case studies of 
companies that have done this?


Many thanks,
