The question is, will this happen in the US? I'm guessing that the regional versions have seperate contracts and that the US version will stick with Ink... The US L$ resales Ink's paid inclusion and IC programs... It's hard for me to believe that L$ US would give up a revenue stream for something as silly as relevancy :)
It's my understanding that looksmart.co.uk is separately owned by British Telecom and just affiliated (co-branded might be a better description) with the 'main' Looksmart. This could be an entirely free-standing arrangement.
