I don't think distributed computing (at least 2 laptops) will help all that much. With a decent card and aircrack-ptw, you can crack 128 bit wep with <40,000 IVs, I've done it with as few as 24,000. That's 2-4 minutes.
if you're intent on doing it, you'd need to develop a distributed computing system...I don't think its worth it.
