The only products where you could probably do this are in the S&P 500 complex: SPX/SPY/e-mini options because you can hedge your vega with VIX futures or ETFs. Don't think DIA or Dow futures have a liquid Dow VIX contract.
But the Dow and S&P 500 are pretty highly correlated, so just use VIX futures or ETFs (VXY, VIXY. etc) to hedge your vol exposure. Just make sure you get your hedge ratios correct.
