the situation i was describing is something like this:

[1] 'very-important-secret' encrypted in ascii armored form to 
unpublished public key using throw-keyid option 

[2] above mentioned message posted anonymously to newsgroup like 
from internet cafe, 
(pre-paid in cash, using new usb drive with nothing else on it)

[3] plausible deniability is maintained, even if entire secret 
keyring have to be given up, with all passphrases
