Accessing USB peripherals on another Mac


I have 3 macs on a wifi network and would like to access the USB peripherals connected to the each Mac from another Mac on the wifi network.

When I connect to the Mac with the USB peripheral using Finder and login (using a admin account), I only see the Firewire peripherals on the mac but not the USB devices (such as USB memory dongle).

Can this be done?
Check out IOGEAR.COM They show wi-fi networking equipment on thier site. I have a wired setup with 3 MAC's wired through an IOGEAR 4 port kvm. I used a 2 port until I added my G5, I gave the 2 port to a friend and it still works fine, so I'm 2 for 2 with IOGEAR.
