It seems to me as classic application of multiple skins.

For example create one skin (basic HTML header, footer)
for "PAJAX" and other for normal HTML. That what I would do.

But this approach is fine as well.

Also small note


>         ___static___ content::master m;



It seems to me bad idea... Multiple threads can
access same object. So unless you make sure m does
not change be careful.
