Another answer:

function Pastebin() range
    let savedreg=@"
    silent execute a:firstline.",".a:lastline."yank"
    python import vim, subprocess
    python p=subprocess.Popen(["pastebin"], stdin=subprocess.PIPE, stdout=subprocess.PIPE)
    python p.stdin.write(vim.eval('@"'))
    let @"=savedreg
    python p.stdin.close()
    python retstatus=p.poll()
    python print p.stdout.read()
endfunction

Requires python support. Use it just like matias' function.
