Eh, hard to say.

 From RFC 3501:
     ... A non-empty
     reference name argument is the name of a mailbox or a level of
     mailbox hierarchy, and indicates the context in which the mailbox
     name is interpreted.

But, later on it says:
     Note: The interpretation of the reference argument is
     implementation-defined.
and:
     A client SHOULD NOT use such a reference argument except
     at the explicit request of the user.

So, email clients are supposed to do
   LIST "" "Shared/*"
instead of
   LIST "Shared/" *

As far as I can tell, the first one does work on Dovecot.  I can get the 
second form to work as long as it's an actual mailbox name.  e.g.,
   LIST Shared/someuser/ *
works just fine as well -- at least with my set up.

So, short answer: yes and no.  Dovecot could return all shared 
mailboxes, but it is not required to do so.
