comment Using encryption schemes for identification
And comments: FMTSeq and similar hashes have support for unlimited signature numbers, but that either brings key schedule problems or makes the signatures terribly big (2^256-ops secure FMTSeq has 10KiB for one signature, for around 1M signature limit...)

Thanks, these two ideas seem to capture where I needed to get pushed :) Thanks for CCA1 mention, I already have CCA2-resistant scheme (Fujisaki-Okamoto padded McEliece) so I guess that would work.
