Investing in ipath India MSCI ETN. Need a broker?

Do I need a broker to invest in ipath India MSCI ETN?

How can I do this cheaply?

Most of my investments are with Vanguard Mutual Funds which means I don’t have to pay a broker.

Thanks!

I’m not sure what the alternatives would be. Do you mean something like a DRIP (div. reinv. plan)? Are you sure Vanguard doesn’t already have something comparable? Does it have to be the India MSCI as opposed to some other India focused fund?
