The only downside is that this does render the legacy base obsolete. But
this is probably not such a great hardship. It might even be a benefit
as people are more likely to upgrade for higher security.

The only concern I have here is if moving to SHA 256 might create
problems with crypto acceleration hardware. I don't think it should, the
hash is usually done on thehost processor rather than the cryptobox, but
I would be happier if folk could confirm that this is the case.
