That is exactly what I have in mind for some time now (and talked
about it at the Tokyo BOF).  I call it for now the GPA (..Agent).

In a first step I will do an internal API for GnuPG to separate tasks
which require the secret key form the other code.

Someone from gnupg-devel already played with GnuPG and a PalmPilot.
One problem might be that these handhelds are a little bit slow; some
specialized hardware for them would be nice.
