Hmm, but if we're being pedantic wouldn't there also be 0 usable addresses in a /31 once network ID and broadcast have been reserved?
It's a subnet containing two addresses, both reserved. You can use the remaining addresses however you like :-) Or, since you know that you and old mate at the other end are by definition the only two nodes on this network, you could just agree to talk... IPv6 has RFC 6164 (and RFC 6547 explicitly consigns RFC 3627 to the dustbin of history). IPv4 has RFC 3021.
