Personally, I always assumed Mr Daniels on Enterprise was with the Federation, but others seem to think he wasn't. As proof, they claim he never spoke of the Federation in the present tense and he spoke of a Federation monument, which supposedly means it must be a thing of the past.
Daniels only said he wasn't a member of Starfleet. It's most likely he's from the future DTI so that makes sense.
