Yeah, there really isn't any way to assign them automatically on other computers.

There is if you use Powerpro. I use the following startup script:
local DrvLtr = select(pprofolder, 3) ; selects the drive letter that Powepro is running from
local string = "T: " ++ DrvLtr ; build string to send to the subst command line
local ed = DrvLtr ++ ?"powerpro\substt.exe" ; renamed subst.exe to fool restrictions on work computer
do(ed, string) ; Assigns USB drive to T:
If you had any other utility running that reported back the drive letter you could use subst.exe from a batch file.
