trying to get iterm2 + vim + screen clipboard integration

gistfile1.txt

# iterm escape code to allow clipboard integration
https://code.google.com/p/iterm2/wiki/ProprietaryEscapeCodes

# do this in a non-screen terminal, it works!
printf "\e]50;CopyToClipboard\a...followed by text followed by...\e]50;EndCopy\a" && echo && echo 'clip...' && pbpaste

# problems
1. vim --version
-> -clipboard -xterm_clipboard
2. passing thru escape sequence in screen. maybe via termcap? or some other "carve out" for that escape sequence?
