I just want to point out something else...
For a hunting expedition, you need two things: A way to get there, and a base to operate from. I have ideas, but as the satement goes, no more outside authors. So, zipped lips. ;)
Now, I know this is outside the purvey of the Fulcrum series, but... since it's brought up, just keep in mind that it's never the intention of the series to follow that plot point. In-canon Gryph already has a huge task ahead of him just to prepare, and who cannot say that he's doing it right now? Just consider the time spent in Fulcrum to be an indicator of the Herculean task of juggling this, and the daily demands of IPO/Experts at the same time.
We'll see the end of this particular back-thread soon enough, just give writer Gryph and Co. the opportunity to get to it when they get to that point. Never rush someone when they're writing a good story. I'm already hooked on Fulcrum, and I have this feeling Len is central to the back-thread once when he's ready. (I blame William Gibson's Idoru series for that.)
