Wow. I've been playing with APLs on and off for a while now, so I'd be very interested to hear more (e.g. where one finds such offers). Any chance you'd be up to chat? My email's in my profile.
It's not just knowing an APL though -- far from it. For the chi/nyc it's a mix of hardcore low-level stuff, and some market knowledge. For the west coast, a mix of low level stuff (less hard core) and more distributed systems stuff.
