Yeah, that is going to be a task that even Hercules would probably go weak at the knees with. I don't really forsee anything happening at all with this until at least the next parliament... especially with the current political climate.
Gordon Brown is pretty much focused on things that are going to make him popular again, in light of mutterings about a leadership challenge and possibly a new PM. No one likes him. And David Cameron is too busy trying to be Mr Nice Guy... which leaves the Lib Dems, who might as well be farting into a hurricane for the amount of attention they get. So I don't think this is going to be a major issue on anyone's political radar for the forseeable future.
Beware the dreaded "Lack of parliamentary time".
