[OpenID] Automating the user's selection of OP

[SitG Admin]

To minimize a selector's surface area, while also minimizing the 
amount of user involvement that would be required for it to work, the 
server could send some Javascript to outsource checkid_immediate (or 
equivalent functionality) to the user's browser; the browser would 
request some secure (access restricted) area of the first website in 
a list provided by the RP, then move on through the list as it 
received access denied errors, but serve up a customized login 
suggestion screen for that OP if the response suggested that the user 
had an account with the OP already. All connections would be done 
from the user's browser, through their connection, sparing the server 
all this work (but pinging OP's every time a user ran the script).
