Yes, since it can be implemented in Emacs Lisp.  The idea of "proving
some work has been done" is what's important.  Plus it's not a
well-known algorithm so there's a low chance of random spammers
implementing it.

That's how hashcash.el (now removed from Gnus) operated IIRC.  But
there's no reason we need to do it that way.  See
http://www.gnosis.cx/download/gnosis/util/hashcash.py for an example
implementation.
