True. Though if there is no secondary connected, either because it's not
there yet, or because it disconnected, that's an easy check. It's the
network lag/stall detection that's tricky.

Oh $Deity no. I'd never suggest that. I just tend to be overly verbose,
and sometimes my intent gets lost in the rambling as I try to explain my
perspective. I apologize if it somehow came across that anyone could
just flip a switch and have it work.
My C is way too rusty, or I'd be writing an extension right now to do
this, or be looking over that patch I linked to originally to make
suitable adaptations. I know I talk about how relatively handy DRBD is,
but it's also a gigantic PITA since it has to exist underneath the
actual filesystem. :)
