My estimate is within next couple of weeks / > months. But it won't be years. Ok, week or two would be ok, couple of months is not. And all I need is single hook in common structure. So if g_endpoint_config hook looks sane to _you_, I suggest we simply proceed. Now, maybe Mauro Carvalho Chehab or Laurent or Julien will want a different solution, but then... they'll have to suggest something doable now, not in couple of months. Does that sound like a plan? Mauro added to cc list, so we can get some input.
