Generally, I like more informative profiles, but specifically with resumes, I don't think it's a good idea. I get the feeling that it'll help bump up the noise as individuals come here to post resumes and then try to enter conversations for which they are unqualified to speak.
How about a special "Hacker News" hash that I can hide in the resume along with my profile name? So if anyone cares to find my HN profile and/or my resume, they'll just have to search for that hash+username to bring it up.
Simple solution: require X metric of participation before you can post a resume (or before your resume is searchable, take your pick). That could be owned account for N days or N karma or whatever you like.
(Personally I don't know if "Don't let lurkers solicit opportunities" is desirable but, eh, simple to implement if you decide it is.)
