Yes, that would be worth investigating.  It's not *quite* the same
language as simpletal AIUI, but our templates are pretty simple so it

Yeah, it was the annotation pages that tended to get very large (I think
some were ~70 megs of HTML).  Perhaps it's better now, but it made a
difference on LP when we changed to streaming.
