strange flash of proto-memory; I get these for internal use only emails all the time these days and have noticed that there's a shortcoming when it comes to fancy palm or desk-based calendar software that bridges the public private gap. It makes me realize that the SIP protocol has potential implications way beyond telecommunications as we think of it (the protocol more than telecommunications generally) now. Does this make sense? Do I really want my coworkers to know I'm going to see the minutemen documentary in San Pedro Friday? (no, but I do want my friends in LA to know I'll be there) Do I really want people outside of my office to know I've got a particular ex-parte scheduled at a particular time? (no, but there are people in my office that I wish could feel free to join in if time allows or pull me away if necessary) I need more scalability of privacy regarding my schedule than I'm currently offered. I should be able to tie all of this into a master contacts and calendar database. Really.

Is this an unreasonable request?
