Re: APT: how to dwnld already debs...
You can repack your installed .deb's with dpkg-repack.
You could also mount the CD on officeMachine (or use ftp) and copy the .deb's to the zip drive.
I have a simmilar set-up and use the above two methods. Sometimes a deb gets left out, but apt will let you know when when you try to install....
If you are looking to simply mirror officeMachine to homeMachine you could simply set-up officeMachine then tar everything to the zip drive...tar -M -cf /dev/<zip drive> will create a multi-volume archive.
