I don't think so - in chapter 1 (Overview and Rationale) it states
"Also, IDLE only applies to the selected mailbox, thus requiring an
 additional TCP connection per mailbox"

... and later, in chapter 3.1:

"The client can also request notifications on other mailboxes by name
 or by a limited mailbox pattern match.  Message-related notifications
 returned for the currently selected mailbox will be those specified
 by the SELECTED/SELECTED-DELAYED mailbox specifier, even if the
 selected mailbox also appears by name (or matches a pattern) in the
 command."

I cannot find any indication that multiple IMAP connections are required.

Well, this is probably a chicken/egg problem ;) One of the core
developers of K-9 Mail says:
"I've been interested in implementing IMAP NOTIFY in K-9 Mail, but will
 only do it once dovecot supports it."
