an updated howto on a portable/usb cygwin installguide?

[Tee]

I noticed with your setup I'm stuck with 

[loggedinuser]@[hostmachinename] ~

as my prompt

is there a way  to change the $user variable without editing /etc/profile  ??

mainly to intercept that pesky USER="$(id -un)" to change it to something of my
choosing in the bat file?
ie Tee@[hostmachine]
more specifically to convince the shell that "$(id -un)" or $USER is "TEE"?
