[Monotone-devel] What key does sync use?

[hendrik]

The description of
    get_netsync_read_permitted (branch, key_identity)
says
    Returns true if a peer authenticated as key key_identity should be 
    allowed to read from your database certs, revisions, manifests, and 
    files associated with branch; otherwise false.
and there's similar language for write_permitted.

Now, when I'm syncing with a server, presumably it's the 
server that vets keys provided by the client.  When I issue 
the 
    mtn sync
command, where does the client obtain the key(s) it's sending 
to the server for approval?

And since sync is a two-way operation, where does the server get its 
key(s) to provide to the client?
