I use this setup (at least I'm experimenting with it).
A secret keyring, revokation certs, etc. stored offline, a copy of the
secret keyring on floppy with the primary secret key striped (only with
subkeys), and no (empty) secret keyring on connected machines, with the
following gpg.conf options:

  keyring ~/.gnupg/pubring.gpg

  secret-keyring /floppy/secring.gpg
  keyserver-options auto-key-retrieve ...

And with a /floppy/pubring.gpg with only those keys (locally/ultimately)

And when I need to work on the floppy keyring, just use
"gpg --homedir /floppy" (I have a shell alias for it) and/or
"--no-default-keyring". And with autofs, I ever don't bother with
mounting/umounting the floppy (it's a ext2fs; I refer here to a floppy
for simplicity, but in fact is any removable media).

A related question: there is some tool/script/whatever to automatically
prune from the keyrings those keys with only self-signatures, or some
way to list them (and only them) with gpg?
