Wall Street firms increasingly are buying into Linux, but some still need convincing that open source licensing and support models won't make using the technology more trouble than its worth.

Harsh economic conditions tend to accelerate technology shifts, so the top brass at Red Hat were a pretty chipper bunch as they explained to Wall Street how they intend to make money in the coming years.
