[cap-talk] capability-enabled spatial databases

Can someone list the capability-enabled spatial databases? I am
thinking stuff like Second Life, Open Croquet???, E-Monkey.
Specifically, I am looking for the protocol which clients communicate
with a database server. I guess Second Life uses a form of XML, I'm
not sure what either Open Croquet or E-Monkey use. Would a typical
spatial extension of SQL w/ SSL/TLS/PKI qualify to be a capability
protocol, if it used swiss numbers for point, polygon, object,
collection and class information and you couldn't manipulate the
database (CRUD) without using a swiss number (specifying a single
thing)? I am thinking that there might be a local client cache
database for stuff like scenery, and the server could update the
client cache. What's the best granularity to keep capability
information at? Point and polygon seem rather low level, but it
seems like you could easily enable them.
Does anyone have code for generating database IDs (say mysql) which
are swiss numbers?
