There's an sha-1 egg and HMAC isn't that hard to calculate. I've rolled
my own quick&dirty sha-256 HMAC once before; the code for that is part
of this snippet: http://wiki.call-cc.org/drupal-xml-rpc

Maybe someone (you? me?) ought to make an hmac egg which can accept
arbitrary message-digest objects.  This would make it trivial to get
HMAC for any type of hash algorithm.

Cheers,
Peter
