If you mean the C compiled code, that's what a typical sbcl binary is already. On my system it's around 2.5MB. The compiled CL code image (and its related data) is around 50MB. save-lisp-and-die sticks the image into the runtime binary.
In mid-2007, Amazon.ca listed Lisp in Small Pieces, an $85 textbook, for $3.95. A guy I know ordered it at that price and it was fulfilled without incident, so I posted it to my blog at http://xach.livejournal.com/133661.html - it quickly became the #1 seller on Amazon.ca for the day. Amazon cancelled the orders and gave everyone a $10 credit.
