Saving files

My class has just finished working through Chapter 1 of the textbook and some students have already developed pretty impressive animations. The problem is, they're huge; one is 7.1 MB.

Since they need to transfer these back and forth to their home machines, we're going to start having problems with them using too much space in their online folder that's web accessible, and kids with dial-up connections are going to get frustrated.

Since it appears that most of the size is the objects, and the objects are already installed with Alice, is it possible/feasible to get a smaller file size by just including the information you need that's not already internal to the objects? When someone tries to open it in Alice, it could say "You're missing _______ from your object gallery. Please download it before trying to open this file."

In my view, this should be the default file format, with another option to save all the objects as well. Otherwise it seems we're wasting a whole lot of bandwidth.
