Arduino ISP

I have a question regarding the ArduinoISP bootloader shield and was hoping for some clarification...

http://www.adafruit.com/products/462#Description

My understanding was that to bootload the receiving circuit required the 16mHz crystal in place, but the ISP shield does not have a crystal connected to the bootloading ATMega. I'm guessing I am incorrect in that notion, and that I could use the shield to bootload then transfer the chips to my circuit (with the crystal in place) and do the sketch uploading there.

Thank you

I think I may have answered my own question, I just saw the Digital Pin 9 to ATMEGA Pin 9, which from what I gather is providing a clock signal

When you program a microcontroller, the ISP runs the show. In that setting, the chip being programmed is just an SPI slave being told what to do.
When you void a product warranty, you give up your right to sue the manufacturer if something goes wrong and accept full responsibility for whatever happens next. And then you truly own the product.
