On the AutoCAD 12 bonus CD there is a program called protect.exe that
will do what you want. It isn't really a compiler, it just encrypts the
file.
If you are really serious about protecting your code however, this isn't
to way to go. Protected files can be unprotected fairly easily. (Don't
bother
asking me how, because I'm not telling!)
There is also a program on the bonus CD called kelvin.exe, that replaces
all
of your variable and function names with random characters. It also
destroys
the formatting of your code. Kelvinated files also seem to load alittle
faster.
There is also a AutoLISP compiler, called VILL, available, but it costs
over
$500 US. Way too much for the casual lisper.
That said, if you just want to share routines with your friends, why not
give them the code? Working with others can be a great way to get new
ideas and lead to a better application.
Just my two cents:

You must not have much to do, huh?
