I don't know if this would come under a multisite hack or something else. My plan is to move one of my sites back to a home DSL line for more reliability but I'll give up some bandwidth.

I'd like to keep the higher bandwidth but less critical modules on the hosted server. Photo albums are my 1st concern.

I tried running the remote module under an iframe inside a content module. That seems to work rather well but I'd want to pull it over with a different theme since I won't need the remote's content other than the targeted module (headers etc just waste space). Once I make this permanent that is easy to do but it would be nice to call a bare bones theme on the fly. Any ideas for doing that?

For things like the photo album I can deal with the possible double login for those that upload pics but it might be nicer to have that automated if possible. Easy enough to duplicate the user base (done) but that doesn't automate the authentication.

Any ideas out there?
