By transactional count given that CloudFlare do ECC for their sign-on-the-fly DNS product, Its used far more than people might realize.
I shifted from openssl enc -blowfish to enc -aes256 recently, if somebody can explain why I should make another shift, I would do that.
for the ephemeral session keying in SSH, I would like something of low cost. I used to use ssh -c rc4 for in-house scp commands, the speed difference was visible. I use mbuffer pipes now for things like rsync but they are nothing like as convenient as ssh/scp, but significantly faster.
ZFS moved compression family. If you'd asked me if lzma was going to get traction I would have said no, but it only takes a few people changing code in common use to have an impact.
