Theme specific login redirection? Anyone know of a way within the theme to redirect to a different url after login? 

Theme #1:
Eg. User goes to www.examplesite.com logs in and is taken to www.examplesite.com/front

Theme #2:
Eg. User goes to www.examplesite.com logs in and is taken to subdomain.examplesite.com

I know of modules that allow us to do this for the entire site but have not found a way to do it just for a single theme. 

Background: its for the mobile site UX.
http://drupal.org/project/login_destination would seem to offer a possibility to use custom PHP snippets as conditions for destinations.

So you need to find out which theme is being used. As I cannot fathom how you are changing your theme in the first place, I cannot help you with that.
