Hello Kleprock,
See para 13 of the Home Use Program Terms here:
http://www.microsofthup.com/hupus/terms.aspxThe way I read it, you are not restricted from moving the installation from one computer to another, BUT you are only allowed to install and activate the license on one computer at a time. So, two simultaneous installations are not permitted.
You should check with the IT/software personnel at your company for further details, however.
