Well, surprise surprise, I don't agree with you - although it depends on your definition of a session to an extent.

I think that one of three things will happen - it will stop; it will be 'run' collectively with whoever happens to be in the chair on the night playing the 'MC' (for want of a better term) - as already happens pretty successfully at at least one local venue; the venue and whole nature of the thing will change to become more structured, and somebody is already talking about trying that out.

Personally, I favour the second option and I hope that's the way it goes. I have neither the time or inclination to take it on, particularly in the way you interpret it, although I don't mind doing my bit, as you know.

Gotta go - more in PM if you like.
