After googling and finding little (aside from one company in the UK - same idea, rubbish interface, and more of the consulting model than the tech model it seemed) I did it the slow way and looked at each of the other exhibitors at the last few conventions they've been to, and found little (good companies they could interface with though... endless opportunities).

Their industry is pretty poor with online presence, so its hard to know whether there are no others competitors, or if there are and they've just got poor presence - mind you, that in itself speaks volumes.
