In OpenSim, the ID server is the User Server. In general, the ID server 
is any server out there that gives you an identity and that serves this 
identity to other services. The most important interfaces of an identity 
service are
Login(in ..bunch of stuff.., out ...bunch including masterKey)
string GetKey(userID, masterKey)
bool   VerifyKey(userID, key)

You are bound to that service in as much as you are bound to that 
identity. You only need to remember the N passwords of your N identities.
