## This uses the PastieClient from #528.  I've put this in ~/lib/pastie_client.rb which you will see in the Vim code below.  Change that require location if you put it somewhere else.

## This is the Vim code, I have ruby compiled in, if you don't - do, it's very neat.  If you can't (or won't) then you'll need to write your own macro in Vim to shell-out to the cmdline version, and you'll definitely need xclip or something to read from the copy buffer.  This works by Visually highlighting what you want to paste, and hitting p^P, change that binding to whatever you like.  If you have xclip installed, then this will use that to put the URL into the select buffer:

function! PastiePaste(vmode)
