Yes, you're crazy.
Actually, it's been suggested many times. However, it doesn't quite work
that way.
With USB, there's a master device, and a slave device. The thumb drive is a
slave device. The NXT is a slave device. You can't connect a thumb drive
to an NXT, just like you can't connect two thumb drives together. A thumb
drive could not request data from another drive. And, the NXT could not
request data from a thumb drive.
This is a hardware issue, so you can't get around it with new firmware.
Sorry

| There is a lot of "not quite standard" to existing USB capable products. Some things like digital cameras and thumb-drives get along fine with current operating systems, but most of them have their own drivers available to implement extra features. (...)
