I am actually working on that at the same time. I'm using the same wiki engine I'm building for Magazedia to build the bigger site which collates every product ever made. Which is a large task, let me tell you...
Would be glad to hear more about it - your basic approach, some of the biggest challenges, whatever it might be. Shoot me a message if the mood strikes!
EDIT: just created my account recently and did not realize there is no PM functionality on HN, doh.
