[Zope] Uses of METAL?

[Alec Munro]

Hi all,
I've a few things with Zope so far, mostly using ZPT and python scripts, 
and I haven't found any serious uses for METAL. In almost every case 
that I've been tempted to implement METAL, I've found I could accomplish 
the same thing with ZPT and/or python scripts. My question is: How are 
other people using METAL in serious applications? I would love to hear 
how it is being used by those more familiar with Zope than myself.
Thanks very much,

Alec Munro
