True, just as long as we balance this flexibility with the fact that using 
layers of OO objects does have it's overhead.  I'm not saying that would 
be a big issue here.

Yep, on the con side, though, is template engine changes usually require 
changes to the templates (adding/removing template variables, etc).  That, 
in turn breaks any current themes so the overall value to allowing this in 
Geeklog maybe a bit overstated.  However, allowing modules to use GL's 
abstract template classes to fit their current engine does have some 
value, I admit.  That way modules can pick-n-choose which template engine 
they want to use.  Then my only question is from a end-user standpoint you 
may end up having to learn more on the rules for valid template files for 
each engine...is that oK?

Regardless of what we do, this will all be OO-PHP.  I think all you and I 
are talking about is if we need to introduce a layer of abstraction here.
