This would certainly benefit the Jets given their cap situation...of course it would benefit everyone, but teams struggling to get under/teetering near the max would likely reap the most benefit.
A source with knowledge of the situation tells Profootballtalk.com the league and NFLPA are "scrambling" to increase the 2012 salary cap.
Provisions in the new CBA have left teams with less cap space than they were anticipating, prompting the NFLPA to seek to "re-do the numbers." The league has apparently shown a "certain amount of willingness" to cooperate with the effort because it "doesn’t want the players to think they got a bad deal." A resolution is expected within the next 10 days.
