Yes this sounds neat. This is not easy though, since in TLS
the client sends its capabilities - and the ciphersuites it supports -
and the server responds with the selected ciphersuite.
A way to get over this, is to send an exportable ciphersuite
as the last in the priority list, and if this one is negotiated
then return the error code.
PS. I'm leaving for vacations tomorrow, so have a nice summer!
