Jason,
In your first reply you mention a lot of "we're all good, we comply, we
don't do x etc"
However you seem to have forgotten to reply to question #1 that Arvinder

http://comcrust.com/ is already four years old it would seem enough time to
get an upgrade in place. Our tata upgrades are usually in place after a
couple of weeks.
Thanks,
Bas
