This is going in the same direction as
this thread.
So to sum it up, it is illegal to do this for any purpose. MPLAB is also free at microchip.com I believe the website is. The only real purpose of the CD is to install CBOT (which is a compiler ment for the robot). Distributing the CBOT file(s) is illegal, since MicroChip requires you to pay for it on their site (which I believe FIRST already did when they gave it to us last year).
My suggestion is to find the CD from the previous member(s) who have had the CD, and go that way. This way you won't be doing anything illegal.
