wifi shield + motor shield + arduino

I would like to run my wifi shield and motor shield off of the same arduino board. Is this possible?

If I need an arduino board for each shield, how can I make the two arduino boards communicate.

I'd appreciate any help.

You dont need Two arduino's :) you need to just change the pins assigned if htey conflict we could help you better if you provided us links of the sheilds you purchased

This is good news :). I bought an Adafruit Motor Shield (http://www.adafruit.com/index.php?main_page=product_info&cPath=17_21&products_id=81).

I haven't purchased the wifi shield yet... Is the Async Labs WiShield 2.0 a good option (http://www.asynclabs.com/store?page=shop.product_details&flypage=flypage.tpl&product_id=26&category_id=6)?
