Twice as many as you have IDE interfaces (i.e. 3 on a normal machine assuming that you have one harddisk)

You can create a binary copy of the contents of a CD to a file on the disk with:
dd if=/dev/hdc of=cd_image_1.iso bs=1024K

assuming /dev/hdc (secondary master) is you cdrom drive, 'bs' just sets the block size and speeds up the copy.

Then you can mount this image as if it were a normal CD with:
mount -t iso9660 -o loop cd_image_1.iso /fake_cdrom1

Just get samba to share this directory, and windows to connect to it. This will perform quite a bit better than a normal CD, it's MUCH faster and will be able to cope better with multi-users (i.e a classroom full of kids).

I'm not sure how this effects the copyright on the disk matterial, I assume if you legally allowed to share a CD drive it is no different to sharing the image of the CD via a hard disk. Perhaps this is your home work....

Hope this helps,
Simon W.
