Yeah, and I think it's important to note that there's NOT much incentive for big companies to help us get this right; there's just so much opportunity for them to insert their own little whatever in the middle; so they'll happily partly solve the problem for us, but usually involving phoning home in a way that we don't need.
It seems like lately it's like regular expressions, obscure to many but when you really need it, you really need to know it.
