I've added support for this.  It should be possible to use a method
such as

(nnimap "yourmailhost"
        (nnimap-stream shell))

>From the info pages:

`nnimap-stream'
     The type of stream used to connect to your server.  By default,
     nnimap will detect and automatically use all of the below, with
     the exception of SSL. (SSL is being replaced by STARTTLS, which
     can be automatically detected, but it's not widely deployed yet).
...
        * "shell:" Use a shell command to start IMAP connection.
...
     For IMAP connections using the `shell' stream, the variable
     `imap-shell-program' specify what program to call.

The variable documentation:

`imap-shell-program' is a variable declared in Lisp.
  -- loaded from "imap"

Value: ("ssh %s imapd" "rsh %s imapd" "ssh %g ssh %s imapd" "rsh %g rsh %s imapd")

Documentation:
A list of strings, containing commands for IMAP connection.
Within a string, %s is replaced with the server address, %p with port
number on server, %g with `imap-shell-host', and %l with
`imap-default-user'.  The program should read IMAP commands from stdin
and write IMAP response to stdout. Each entry in the list is tried
until a successful connection is made.
