FOSDEM did not deceive me at all - just the contrary.

There were many interesting things and the talk I liked the most was about valgrind. The very obvious idea after it was "why not develop a security scanner on the top of valgrind?". Valgrind is a framework to develop simulation-based tools, and MemCheck is just one of them. Valgrind handles the most tedious and demanding part of the job - simulating the processor instructions. It also handles the operating system calls, signals, and the rest, so the developer of a security scanner will be able to concentrate on the essential things.

Just an idea..
