Yes.  We have a scheme to make URLs that are nice and small and don't  
have funny characters like "%" that e-mail agents feel okay breaking  
on.  This scheme involves elliptic curve cryptography.  See ticket #217.

Sigh.  This is yet another "shallow" user interface bug.  I just  
created a ticket for it: #401 (command-line: tahoe ls's way of saying  
"No such file or directory" leaves something to be desired).

If you run "bin/tahoe ls --dir-cap=URI:DIR2- 
RO:pgj2oefhipe2uzulz7kyvyfcbe: 
7xoalidet7oignxsnhra77ez7qxh6ro5humhumncabv4cghdkc2q" you will find  
what you seek.

Somebody who loves command-line interfaces and starts closing these  
tickets will be a hero:

http://allmydata.org/trac/tahoe/report/23 # the tickets with  
component = "code-frontend-cli".

(Note: no patches accepted without unit tests and documentation.)
