The idea itself like many throughout the forums are interesting and cool, but it won't really apply that easy to the model we have in the game.
Currently, there is no real worth to the vessels themselves; meaning like how it was for instance in DS9 where Dukat and Kira captured a BoP.
Hate to be perpetual on the phrase but "the game is too WoW-like in mechanics" that boarding hostile player-controlled vessels would simply not make any sense.
For such a neat idea to happen, ship fights would have to be something like Uboot style, a lot more of tactical and slower than hard-n-fast-paced - to begin with.
Coupling that idea with having more players controlling a single vessel would have been cool too, but this too was most likely something that was dropped or simply not possible.
