I would imagine that it doesn't take much bandwidth for signalling at all, but I don't know for sure. Where I bet we run into bandwidth issues will be Always On/Dynamic ISDN (AO/DI). When people start exchanging email and getting PointCast over the D channel, we may not exceed their 16k D channel to the point it wants to bring up a B, but I imagine that we'll have exceeded our 64k D if we're running NFAS with a few PRIs. There's only four pegged 16k D channels of bandwidth in our 64k D, after all... Anyway, brief and bursty as it is, I imagine signalling wouldn't be slowed down appreciably anyway. I'm sure we only have 64k D channels because we have 64k B channels and they couldn't make it any smaller. That's why NFAS exists.
