Thanks for the tip on name service switch extensions -- I shall look..
Maybe adding something that lets you query the users there is all I
need... we'll see.

The AuthorizedKeysCommand could be a script - and figures out
everything - the ssh connection doesn't' get that far when the user
doesn't exist on the system yet :(

Hence  - maybe a NSS User Database extension which looks for the
public keys from a webservice (and then maybe writes them to

The AuthorzedKeysCommand could then just return the tmp/username information..

Hoping the NSS shows some promise.. Wow , thanks for all the help!
