Don't kid yourself. Very few businesses in my experience think about
this stuff when they go to use a hash. Most just use whatever hash
they're used to using. I rarely see clients actually sitting down and
thinking about what the application of a given hash is and what the
threats are in their specific case.

Assuming there are no real-world attacks against your particular VPN
that uses MD5, does that make it safe for the rest of us in any given
application? A rather leading question IMO.
