Very pleased to see this discussion going on ... using HTTP(S) URIs as
identifiers is an incredibly powerful option.  It means opensim can scale
with the Web, and also be highly interoperable with the existing Web, if
that was wanted ( imagine an opensim university with lectures coursework
slides taken from the web, an not needing a browser, example off the top of
my head, or using openstreetmap to generate real world cities )

There was a thread on this topic on the W3C Technical Architecture Group
mailing list, between Tim Berners-Lee and Christa Lopez

I would encourage you to use HTTP(S) URIs where possible, to enable opensim
to be a truly ground breaking system on the Web (not just in the simulator
space)

Note also that with HTTPS you also have the option of securely
authenticating a user using public key infrastructure, for example with
client certificate -- possibly ideal for a rich ciient like opensim
