There's no technical reason to require NAMESPACE. Namespaces are 
server-wide, and can be configured along with other server properties in 
the configuration file.

Ignoring NAMESPACE and configuring this in the configuration file has 
other advantages as well:

- You get to limit what namespaces are available in RC.

- You get to give the namespaces "human" names. Depending on how the 
user interface will allow navigation of shared folders, this will be a 
huge advantage. Examples of namespaces are "#shared", "~" and "news"; 
not really strings that belong in a user interface. The configuration 
could allow these to be named, for example, "Public Folders", "Shared 
Folders" and "News Groups".

Probably, but they probably do not support any sort of shared folders.

The literal string "INBOX" is defined by the IMAP specification to 
always refer to the authenticated users inbox. So a folder named 
INBOX{delimiter}INBOX would be a sub-folder of INBOX confusingly named
