You're stuck up there if you ender pearl up... well, I mean you have to build a portal to leave if you don't want to exit without saving.
As for spawning.. It was one of the first things I tried after the new update. It seems that currently nothing spawns on top of the nether. I made a stone brick platform at about y140 and flew about 50 blocks above it and waited about 5 minutes...nothing spawned. Perhaps someone else had a different experience but as far as I can tell no mobs will spawn above the nether at the moment.

Let's just leave it at... I wouldn't plan on saving your game up there if I were you...

meh... I suppose IF you happened to have had the foresight to have brought 10 obsidian and a lighter with you.... you'd have a way out....
