The problem with portals isn't, as I see it, just coming out, but going in as well. When a portal is made in the Nether, it makes the portal on the nearest free space at that point. This free space could be above, below or beside where it is in the normal world. Because the Nether is 1/8 scale of the normal world(but not a model, as in it's different and completely incompatible) that only makes the portal out further away. On top of that it would have to go in a place in the normal world that was not occupied, so it could be further still. The only way to fix that would be to make the portal either destroy or place, as the case may be, blocks at that very point in the Nether, or for you to go into the Nether and make the necessary changes yourself, then make a new portal out. It would be dangerous to have the portal destroy blocks because you could make a portal in the Nether and have it destroy that awesome new castle, you spent weeks building, when it makes a portal in the normal world. With the random world it would be very hard, if not impossible, to make it work perfect. So instead of making a portal in the normal world and hoping it goes where you want it. You could study the Nether and make a portal from the Nether to the spot you want it, in the normal world, from there. Much more work, but when it's done, it would actually work. Of course with the 1/8 scale it would be very hard to even tell where you are without making a whole bunch of portals. Portals that could go anywhere around the vicinity of where it was made. Hm, it would be easier to just walk, or die when you wanted to go back to spawn.
He could make it so it doesn't create a new portal in the normal world at all, but then fast travel would be impossible without some sort of pointer system. Where the player makes one portal connect to another. Though, if there were a bunch of different types of redstone, you could place one kind of torch on each portal, to make them connect to each other. He could even make it so you could portal to any portal from just one portal, by making it so if you place a torch on the portal, it will go to the other portal with a torch of the same color(more than two portals with the same color torch wouldn't work). Making it so you could portal to anywhere in your world from your spawn point, without having to walk at all. That would make it so you would have to have been there in the first place though. To make the portal and place the torch. No going to far away, unexplored lands. I guess he could make it work both ways. Just make it so if you want to connect two portals, so they always link to each other, you have to place a torch of the same color on each.
