--- Comment #3 from Damien Miller <djm at mindrot.org> ---
Unfortunately this isn't trivially possible - in the SSH protocol,
compression is negotiated before the authentication, and it is only at
the authentication stage that the server learns the name of the user
who is connecting.

It is theoretically possible to force a rekeying operation after
authentication to renegotiate the encryption/compression options but
this is expensive and IMO not worth the complexity needed to implement
it.
