Like Amoafwl, I'm curious about the logistics of the 4 year separation. Sounds like Chinese water torture.
For NGS, if you're interested in working on that aspect, I suggest you find an official NMMNG meeting, or an unofficial NGS support group. Being with a bunch of like-minded guys can be really helpful. Let me know if you need more info on that.
