def check_channel_shell_request(self, channel):
return False<EOL>
Determine if a shell will be provided to the client on the given
channel.  If this method returns C{True}, the channel should be
connected to the stdin/stdout of a shell (or something that acts like
a shell).

The default implementation always returns C{False}.

@param channel: the L{Channel} the request arrived on.
@type channel: L{Channel}
@return: C{True} if this channel is now hooked up to a shell; C{False}
    if a shell can't or won't be provided.
