It certainly can be used for other tasks. At CERN we have programmed both processors on the Tigon2 to act as a traffic generator & measurement tool to test switches. We use lots of cards in parallel to drive all ports on a switch. It's given us much more useful results than the expensive S*******s tester.
We even went so far as to build a Tigon2 development kit for Linux, and got about 5% better performance just from using a better version of GCC and linker tricks.
The Tigon2 cards are wonderful because of our ability to program it however we like, and I really hope we can build similar interesting devices from a crop of someone's Tigon3 cards.
