I don't think the hub flex coupling will work since the crack is right at the fitting. That coupling can only join pipe to pipe (not pipe to a pipe fitting).

No you are wrong.
There's more than enough flex in the coupling to ensure a water tight seal. We are talking drain lines not water under pressure. While this is not the greatest fix it sounds like something the homeowner can handle.
The proper way would be to replace the whole assembly or drill out the broken pipe section and replace.
Hmmm ... ya know that just might do the trick. However, you still have the A/C evaporator improperly tied in. You could try to install a P-trap in the condensate line but, it might get sucked dry by the main pipe.
A plain neoprene coupling...
Not exactly what I would recommend....
Stick with the banded coupling that I mentioned earlier...
The additional support from the band will keep the pipes lined up properly so that the line doesn't clog...

No Toadfish you are wrong...
Murph52 is correct the couplings are designed for pipe to pipe connections only and that is the only approved use under code....
Seems like replacing this assembly isn't that much harder or more expensive than using one of these couplings, and it is a nice, relatively simple, first project since it's just replacing what's already there. Replacing the assembly would also possibly give the OP the chance to convert that existing s-trap into a p-trap-- that's a bigger siphon concern to me than the (future) a/c trap.
For the a/c, as long as it's a 2" p-trap I think it should be safe from siphoning. The catch is joining abs and pvc. If it were me, I'd set it up as an air gap drain (like a washing machine drain): build in a trap between the wye and a new 12" vertical 2" drain. Then just sleeve a few inches of pvc in the top of the abs, eliminating the need for a reducer and any cementing. The only (tiny) concern in my mind would be that the trap would evaporate dry in the winter.
They make a tool now that is designed to drill out the pipe from a cemented joint. I'm pretty sure it's called a "Hub Saver" but go in to any plumbing supply house, not the big box stores, and they should have one. I've used it and it's saved me a lot of time and work. Cut the vertical pipe about 2' above the crack, and directly above the hub of the fitting. Use the Hub Saver as directed...make sure to hold the drill in a VERY straight line to the hub. Glue a new 2" piece of pipe into the hub and install a using a Fernco or repair union (connector) at the top.
