Yes, good points, and agreed.

Hopefully there are ways to lock down Genshi (or these will exist) at 
some point in the future to enable such locking down. Or perhaps we will 
need to look into other templating languages to support these scenarios 
instead.

By the way, it's interesting to observe that Genshi is developed (at 
least in part) by people at Edgewall, who also develop Trac. To develop 
Trac, Clearsilver was used, which is a very restrictive (and very fast) 
template language that is very "push". Genshi, I understood, is in part 
a response to the limitations of Clearsilver.
