Wifi on internal connector?

Hello,

I'm really interested in mini2440 device, but I need a wireless
connectivity.

As I need an integrated system, an external wifi module + a USB hub cannot
fit my needs.
I would like to know if it is possible to connect the wifi module on an
interal connector (interal USB ?) 
In fact I need the USB port for other devices.

I would also appreciate if you can explain the pros of using your wireless
module, and not an USB Wifi key.

Thanks in advance for your help
