afaik the ID is the key ID. When you do gpg --list-keys you get something 
like:
pub   XXXXX/YYYYYYYY YYYY-MM-DD
uid                  Name <email>
sub   ZZZZZ/AAAAAAAA YYYY-MM-DD 

The 'YYYYYYYY' in my case is the key. 

Also setting the environment variable GNUPGHOME  (thanks Stefan :)) might 
help you find the right .gnupg directory.
