All,
I appreciate the responses. I'll contact him and tell him I am 50/50 on the frame/wheel set combo being right for him. I can probably go to Ksyrium Elites on the wheels and he'd be OK there, but I think the frame's a little iffy, and I definitely know the fork is twitchy.
Since the thought of him on a steel frame raises no such doubts, I think that's his best option, and I'll tell him so. He's a nice guy, and I think he'll like biking, once he's properly fit on a good bike.
Thanks for everything, folks.
