Thanks for creating the patch. Sorry to nitpick but as has been brought up
before, it's better to send patches as email attachments (that is, not as
a links to external sites).

Also, it would be helpful if your patch is submitted as a diff over
applying Michael's patch. That is, only the stuff specific to testing the
multiple sync feature and let the rest be taken care of by Michael's base
patch.

Thanks,
Amit
