Created myiso1.iso from Wheezy(7.1) DVD 1 of 10 using dd and then 
used dd to copy it to a USB flash drive.

I was able to boot from the flash drive and do several installs 
(different DE's).

*HOWEVER* I can *NOT* mount the flash drive to view files. Tried 
file managers that are automatically installed with Wheezy Gnome, 
Lxde, and Xfce. Also tried Gnome under Squeeze. WinXP reports 
drive not formatted. Gparted under Squeeze reports it as unknown 
format but will mount it as /dev/usb0 and file list displayable.

This is unacceptable for y project goals.
I'll be rereading what the Installation Guide says about 
installing from a flash device.

A cut-n-paste of terminal output when creating the flash drive 
attached.
