Jaime has gotten these drives enabled on all the public terminals in GPL and BusRef. On GPL CD workstations, the plug for the USB drives is in the back of the CPU, slightly blocked from view by two small cords (one white, one green). It's not hard to find though.
This means users have options other than Zip disks or FTP on GPL computers for saving. In BusRef, it offers a simpler alternative to burning a CD.
