Where does the keyspace come from? rot13 has no keys.
Of course you could do rot2 - rot24 and all the other combinations. Is that were the factor 25 comes from?
The deep inspection needs to look only at the first couple of bytes of each new a TCP connection. So it's not that disrupting. After 2 bytes you can already skip for a vast fraction of other traffic.
