I've done it with good results. I vacuumed sealed individual portions and froze. To reheat I dropped the bag in boiling water. You have to keep an eye on the bag though, if you leave it in too long it could burst open.
I have done it 2 ways. First way is in the crock pot and let it heat up slowly if you have the time. The next way is a pasta pot with the double boiler type with two pots and that way to me works the best and it seems to add some moisture back into the meat also. I have heard here that you can boil some water and put it into it to re-heat your pork. One thing that you should if you haven't yet in but a Food Saver unit it's worth it's weight in gold.
Guess you've gotten your answers, freezes perfectly.
If you have a vacuum sealer then you could drop the bags into simmering water until reheated but usually if I have a bunch to reheat I just dump the meat into a large hotel pan, cover with foil and put in the oven at 275 until hot.
I usually just freeze them whole, double wrapped in heavy foil, then into a garbage can. Take out when ready, let thaw, and warm up in oven. Seems to hold the moisture better. I have froze it pulled and it does work just seems to be a little dryer.
