Yeah, sure, it's doable. I do not believe that adding the concept of a Line number to do this is required to do this, or even desireable. > Now you can come up with some very nice UIs that provide > better user experience, if you have a suitable display > instead of just a bunch of lights.

My point is that we shouldn't bastardize the protocol with all this complex extra protocol (Line numbers, BFCP, NOTIFY/PUBLISH-storms, etc.) just do do this. The basic "single-lamp" based approach is doable without any of this. _______________________________________________ BLISS mailing list [email protected] https://www.ietf.org/mailman/listinfo/bliss
