gpg-agent and other passphrase caching tools

[Malte Gell]

I'd like to use some kind of passphrase caching tool with GnuPG 1.2.0=20
and tinkered a bit with gpg-agent 0.9.2.

Is gpg-agent stable enough for use in production environments ? It seems=20
to be part of the Aegypten project, will it find its way into the=20
"normal" gpg tree as well ?

gpg-agent works well as far as I can see, but are there any other=20
similar tools which may be more mature or what are you using ?

Regards,
Malte
