I think that the Starfleet/Bajoran angle is best. Why not Bajorans from Starfleet?
The reason? The non agression pact.
Sisko argued that Bajor couldnever stand against the Dominion, and got them to sign the pact to ensure Bajors survival while Starfleet had to rally its forces.
This of course didn't change the fact that many Bajorans were sympathetic to Starfleet/the Federation. Nor did it stop Rom or Jake Sisko from gathering Intelligence...
Now combine this with the offhand remark from Picard when ensign Ro came aboard the Enterprise.
"Why her? She's not the only Bajoran in Starfleet?"
So we know that over 5 years before there were multiple Bajorans in Starfleet, and that since that time, the ties between the two have grown closer still. So why not have Starfleet Bajorans out of uniform and operating on a covert 'mission impossible' style game...
That way, if they are discovered the Dominion doesn't have a reason to trash Bajor for the breach of the non-aggression pact!
