Ok, see, this is what Leo, Owen and I all think, and maybe a couple others.
But Scott just got done telling me it's *so* much more expensive to
home-run than ring or GPON-in-pedestals that it's commercially infeasible.

Well, I would assume the splitters have to be compatible with the OLT/ONT
chosen by a prospective L1 client, no? Or is GPON GPON, which is GPON?

Hmmm. I invite you, Rob, if you have the time, to look at the Rollup
