Subject Re: Flex -> HTML, Linux and time to say goodbye?

One of my Flex apps is run in a 911 call center. The machine that it
resides on has NO outside internet access, and the application works just
fine with caching.  Even when I updated to Flex 4.6, everything was fine,
including the RSL / Cache.  Even if the world ends today, your apps
published today will still continue to work, and Adobe can't nuke your apps
from afar.

Beta frameworks were never signed, and therefore weren't eligible for the
RSL cache.

The biggest questions are what happens in the future, with future software.
 If you have a static environment (no updates to your SDK, no updates to
the runtime), the world will continue to live in harmony, with your Flex
app happily chugging along.  Updates to either the SDK or runtime may cause
headaches in the future, and that is the big thing to address.  We already
know that RSLs won't be cached by the FP in the future.
