ZMailman queuing

This is just a quick thought about queuing an email thread.
Would it be possible to start and stop a MailMan queuing process from Zope
as a thread?
During this queuing, ZMailman hands off a Zope-generated payload to MailMan.
Zope is then released from the mailing process and continues on its way.
MailMan picks up the payload and starts sending.

Something like this ...

<dtml-sendZMail start>
...
</dtml-sendZMail stop>

OR

<dtml-with ZMailmanqueu>
...
</dtml-with>

ZMailman is acting as middle-ware anyway, so this might be a valuable
capability.
