I'm also on the "there's a way" bandwagon. Most of ours are fly out, 24-30+ hour overnights and red eye back. Commuters love 'em because they get back in at around 6-7 am and they can sleep on the commute home. Then they're in their house before noon on a day that's NOT a day off.
The trick is managing your time before hand. If someone gets assigned a trip at 1300 that ends at 0100, that's not that big a deal. Don't get up at 7 am, go running and not take a nap. I can see the open time and the reserve grid. I know that if I start reserve anytime after 1800, I'm on the hook for a red eye. It's up to ME to make sure I'm rested in case I get a call. Going out to play a soccer game from 2-5 and HOPING they don't call is just irresponsible of me. Hell, the other night all the scheduled red eyes were gone and I STILL got a call to do a delayed MC)-JFK leg because the other crew timed out. They did a tech stop on RSW-JFK in MCO because the scheduled crew was legal for RSW-MCO but not RSW-JFK. So they stopped in MCO, and a reserve crew finished it out. Every reserve should know when they start their RAP, and if they aren't fresh and ready to go by then (and potentially fly a flight they are legal for), they need to call in before then.
Also, the FAA tracks extensions and refusals of FDPs. I know we got a "Hey, what's going on over there?" not too long ago from the FAA because we had an unusual amount of FDP extensions dues to IROPs. So, the FAA DOES hold (at least theoretically) airlines accountable for getting close on the FDPs if they do it too often. My? I've never been asked to extend my FDP since 117 came around. I've been in the situation where I was on duty LONGER than the max FDP because the last leg was a DH, but I've never been put in the spot of potentially refusing an extension. We've got plenty of guys here that are in the "I'm never agreeing to an extension......EVER!" crowd. They tend to be pretty much douchebags, though, to just cover every situation with that blanket.
