However I still suggest solving issues at the appropriate layer, even that has some performance cost. Consider the case where applications add extensions to TCP. In the long term I believe it pays off by having a simple security provider protocol and simple applications that implement it. (not that today's TLS is that simple - and there are already some application specific extensions). best regards, Nikos
