I think <!--#with _.namespace(tempvar=tempval) --> use tempvar here
... <!--#/with--> should do it, although I haven't tried it yet.

_[Category] should give you indirect access to the variable whose name
is the value of Category.  Note the lack of quotes around Category (as
opposed to your code above).

Tell me if this doesn't work for you (and I'll look more into it).
