This could be usefull: Hacker's Bench : Wireless Doorbell Hacking

And you can read this thread too, I remember someone mentioned a wireless doorbell: building usb-remote-cable

Please write a small "how to" once it works!

There are solid-state relays that you could use.

Signal from the receiver closes the relay contacts which then passes the 4.5Vdc battery voltage to the USB cable.

RadioShack.com - Cables, Parts & Connectors: Component parts: Relays & transformers: 5VDC/1A SPDT Micro Relay

Can remove the speaker to obtain plenty of room for a circuit board for components.

HTH,

You can use IR to make a small and simple remote trigger.

For details of one I made:

For a really simple wireless remote see here

All you need apart from the two components (transmitter and receiver) is a 5v supply and small on/off switch and a cable with a USB plug on the end.
