AFAIK, there are two issues, at least if one accepts that anyone was is going to speak or otherwise attempt to influence decisions needs to be registered and, insofar as is possible and reasonable, registered with an identity that is understandable by others. Note that should apply to entering anything into a Jabber room (with a "MIC" request or not) as well as using the Meetecho queue request mechanism. One is the rapid switching Brian mentions above. If one concludes, midway in a WG session, that one needs to speak up or say something on Jabber, the odds are high that the conversation will have passed the topic by if one has to pause and go through a registration procedure rather than just switching modes. That is, IMO, the important issue on a short-term basis. THe other is the cost of doing this remote participation stuff, costs that are going to rise if things some of us have discussed to make things work better or more smoothly are implemented. ISOC's generosity notwithstanding, even some of us who are happily taking advantage of the free ride are uncomfortable about doing so. If, as a community, we are going to understand the costs and plan for the future, we need to have some understanding of who is using the real time facilities and how. Passive listening or video-watching hours or days later is another matter -- we want to have the recordings for historical and documentation purposes and the marginal cost of an extra person downloading or streaming them is rather small. But real-time remote participant, and even remote observer, costs are another matter. IIR, the registration form does have an "I prefer to not register" box. That presumable locks one into Observer mode with no possibility of a real-time switch to Participant. IMO, that is reasonable, important to have as an option, and should accommodate anyone whose privacy concerns outweigh any desire they might have to switch over to active participation. john
