Sebasitian,

This is pretty nice.  I wanted to clarify something.  You said "(of

something in the package that prevents communication between two
images on the same machine, using different ports of course?

"I am crucified with Christ: nevertheless I live;
yet not I, but Christ liveth in me: and the life
which I now live in the flesh I live by the faith of
the Son of God, who loved me, and gave
himself for me."
