   But the situation will be better than the present one...  and this
problem is actually surprisingly rare with the current invalid kinds
used by all vendors in the WAN optimization market. I suppose this is
partly because people don't deploy equipment that breaks their network.
    

I'm also asking whether they deploy equipment that breaks anything for
the end user (and sure, vendors do this all the time - they're called
NAT boxes ;-)
  

    In the terminology I'm used to, vendors sell, end users deploy.

    Many end users deploy both WAN Op and NAT; they just need to be configured correctly (and not do anything stupid ;-).
