SSL, Multisite, Sub Domains and Domain Mapping

Have found a ton of info but nothing with a solution. I would like domain mapping to work on both the original site sub-domain or the mapped domain.

I have already installed a wildcard ssl cert and it works fine for admin purposes. But other than the admin interface, everything else redirects to the mapped domain.

I would like to have MarketPress, Membership, etc... use ssl on the checkout pages using my wildcard ssl cert for the site sub domain and then use the mapped domain for all non ssl pages.

Anybody implemented anything in htaccess or the domain mapping plugin itself.
