My impression is that Stockfighter is a reaction to the fact that recruiters are exceptionally lazy and prefer a basic keyword match on a resume to actually checking anything. If Stockfighter works well then I would guess IT recruiters will do the same thing, else they'll be competing against a company with a tremendous advantage over them and they'll lose lots of their competitive advantage.

To that end, it might be worthwhile starting a company to build something similar to Stockfighter that can easily be whitelabelled for recruitment companies.
