I believe the only place you would be able to get a demo is from the Animation:Master '99 Handbook, by Jeff Paries. It is out of print now, but if you search around, you might still be able to find a copy. (I've recently seen one in the discount section at a local Borders bookstore, for example.) The A:M 2000 handbook which replaced it does not include a demo, nor will any future editions, to my knowledge. Hash no longer offers demo versions, instead, they have a 30 day money back guarentee when you purchase the software from them. Hope this is useful to you.
