Sounds like they have you and the box pretty well tied up.

Any work around is going to be seen as a security breach by the IT folks and as indicated by bluejaywpg my prove expensive.

An approach might be to set up remote access to your home computer on some unblocked port and use that to download and transfer.

All in all probably simpler to load up an MP3 player or CDR at home and then just drop them into you work PC, not much of a challenge tho, unless they search you upon your arrival at work ;-)
