program an ATtiny85 microcontroller using the Arduino?

Found this guide on program an ATtiny85 microcontroller, but is says:

For this tutorial, you’ll need a Arduino Uno or Duemilanove (w/ an ATmega328, not an older board with an ATmega168)

But what if iv got a Duemilanove with an I still use it as a ISP for the ATtiny85?

I believe the answer is "yes". The only risk is that the 168 will not have enough Flash or SRAM but I don't think that's a problem.
