I think this could probably be handled using crowd sourcing approach within a company. The problem that I see with typical job postings is the tendency for people to over-tailor resumés (as is mentioned in the article).

I mentioned it in another comment already, but this problem is what I'm tackling with They Meet You (http://theymeetyou.com). At a minimum, I'll be using it where I work, but check it out if you want.

How it works is really simple: You can send a message to anyone that proves they work for a company, if you interest them then they can share their contact information with you.
