I know than it's a really old question, but if someone is interested in this feature, can check this code http://vim.wikia.com/wiki/Auto_highlight_current_word_when_idle

" Highlight all instances of word under cursor, when idle.
" Useful when studying strange source code.
" Type z/ to toggle highlighting on/off.
nnoremap z/ :if AutoHighlightToggle()set hlsendif
function! AutoHighlightToggle()
   let @/ = ''
   if exists('#auto_highlight')
     au! auto_highlight
     augroup! auto_highlight
     setl updatetime=4000
     echo 'Highlight current word: off'
     return 0
  else
    augroup auto_highlight
    au!
    au CursorHold * let @/ = '\V\<'.escape(expand(''), '\').'\>'
    augroup end
    setl updatetime=500
    echo 'Highlight current word: ON'
  return 1
 endif
endfunction
