Nether reactor in 0.5.0?

I read a bit about it and so far all I know about it is that it spawns zombie pigmen. I hope it will get more purpose and maybe give you nether items. I also hope that Johan will reveal more about it before 0.5.0 comes out. Please leave your idea on what it will do in the comments. So now as a good idea , I might make building tutorials for mobs for those who like legos. For those who are waiting for their skin request, I will make them.
