All good points :)
I think sometimes people forget that I am a big promoter of Guvnor and
always have been. That said however Guvnor IMO is not a CMS and is not
very well suitable for HA of static content (or really HA of any content
as it is right now, I'm sure this will be much better in the future).
Thanks.
