Please continue with this.  I do a ton of animations, but they are for my friends and family, and have been doing so for years now.  I would love this software.  $2000 or even $3000 may seem like a lot of money, but I have been wanting something like this for years.  I would gladly pay several thousands of dollars for it.  :)
Please, Please, Please don't stop working on this....  this is very cool.
