Ah,.. too bad :-/
I've read some emails from a guy here that currently seems to do some 
hacking with gpg, perhaps he can help me (@Chris: plz contact me 
directly as I'm not subscribed to the list).

btw: It's pretty bad that one can't change the preferrence settings for 
his subkeys (or is this possible?). I'm havin a key with one email (UID) 
for different roles. But each role is using a different encryption 
subkey. Now in the office my machine is very slow and if someone sent me 
a big encrypted file (for the office subkey),... it takes very long. So 
it would be nice if one could specify these things for the keys to 
(perhaps in the selfsigs of the subkeys?)
