I use a 4096 byte RSA PGP key; since SSH also uses the RSA standard, is it at all possible to use the PGP key as an SSH key without installing additional software on the server (and as little as possible on the client)?

There are several ways, which may or may not work:
gpg2
on Debian comes with agpgkey2ssh
tool, andgpg-agent
can act as a ssh agent too, but I couldn't figure out how to actually make ssh use the key for authentication.
