I am setting up a system that will allow me to host multiple domains from the one wordpress install.
I am able to style each blog / site using a css override, so they all use the same theme, but have their own CSS to make it look different.
I now have a requirement for custom HTML in the header and or footer of some sites.
Am I best to
A) set up each site with it's own theme (which i think would be inefficient for scaling - i plan to use this for hundreds of client websites)
B) deploy some kind of localisation plugin that would allow me to use a local header / footer per site.
?

I'm certain this problem will have arised before, but I can't find anything with the search or plugins.
