I think that depends on the sitution. For a social sim, it's optional. For a game, it would be mandatory and assigned on log in. The ability to affect these parameters would themselves be under access control, but that's a separate issue from the mechanism used to express the context. I would expect that in the absence of parameters or context, you get the default view which would be everything. > An optional view would reflect user preferences, such as AOI > parameters or versioning.

The idea of it being an "environment" is what I've been leaning towards, possibly even an extra parameter passed in the message that basically means, "if you need more information, check this vobject". Another possible mechanism would be to use the vobject source to look up the correct context to use. In either case context would presumably be implemented as a vobject with a child property for each parameter. -- [ Peter Amstutz ][ [EMAIL PROTECTED] ][ [EMAIL PROTECTED] ] [Lead Programmer][Interreality Project][Virtual Reality for the Internet] [ VOS: Next Generation Internet Communication][ http://interreality.org ] [ http://interreality.org/~tetron ][ pgpkey: pgpkeys.mit.edu 18C21DF7 ]
