Camra's official position is summarised here: What is live beer? So, KeyKeg craft beers should all qualify for Camra purposes.
That's my main problem too, apart from usually being served too cold, and often with more carbonation (albeit natural) than most cask beers.
And the same point has been made to me, but I would expect somewhere selling a good range of craft beers to people who are generally interested in the subject to make that clear at the point of sale (which a few do on screens or beer menus, so it can be done).
