get your facts straight. a "legal business in the U.S." is not the  
same thing as a "telecommunications carrier".

you are correct about what section 103 says.

however, read in section 102 (47USC1001), where they define the term  
"Telecommunications carrier".

subsection (8)(B)(ii) is kinda vague- apparently, if the FCC decides  
that an email server is a "replacement for a substantial portion of  
the local telephone exchange service and that it is in the public  
interest to deem such a person or entity to be a telecommunications  
carrier for the purposes of this tile", then anybody who runs an email  
server would be required to make provisions for government wire-tapping.

so... did the FCC declare email servers to be part of the telephone  
service, and nobody noticed?

subsection (8)(C)(i) explicitly says that "information services" are  
NOT included. subsection (6) defines what the term "information  
services" means... and (6)(B)(iii) sounds like an email server to me.

in addition, subsection (6)(A) seems to indicate that the term  
"information services" would include encryption and decryption (they  
are "transforming", after all), which means that they would also NOT  
be covered under the CALEA law.

so my semi-educated but usually correct guess is that, unless they are  
providing connectivity to clients, hushmail is not a  
"telecommunications carrier" and therefore are not required to make  
any provisions for government monitoring.

if they ARE providing connectivity, that's a totally different story.  
the fact is that they have your secret key on their server. it may be  
encrypted so they can't just plain read the key data, and they read  
the passphrase for that encryption wrapper from a web browser whenever  
they need to do something with the key. if they WERE considered to be  
a "telecommunications carrier" and received an order to monitor a  
user, they could easily change their scripting so that the first time  
that the user USED their key, the script would decrypt the key itself,  
and then make a copy of the un-encrypted secret key data, and then de- 
crypt anything in the user's account.

personally, i wouldn't use hushmail anyway. i prefer PGP/GPG, where  
the secret key never leaves the computer sitting in front of me. if  
hushmail didn't have the secret key, then they wouldn't be able to  
provide any de-crypted information, regardless of whether they can  
convince a court that hushmail should be considerd a  
"telecommunications carrier".
