The main problem I've had has been distribution. To distribute a lisp program I need to either:<p>1) Create an executable image that is HUGE, even for small/simple applications<p>2) Distribute a loadable image and force the users to make sure it's version matches their runtime (if they even have one, which isn't likely).<p>Perhaps there is a third option... and if there is I'd love to hear it. But if you can't distribute the program, whats the point in writing it?
