Great, thank you. We will try this out and report back.

I used to have the same concern (we are shipping Genworks GDL as a
commercial package as well). But then I realized that Quicklisp does not
automatically download anything new; one of its big benefits is that it
gives you a consistent (and in theory mutually compatible) snapshot of all
the libraries you load for a given month.

You have to explicitly "update-dist" to make it update itself with new
versions of everything.

And for delivery (we ship a commercial product as well), we don't even
include Quicklisp or ASDF in the build. We _use_ Quicklisp and ADSF to
_prepare_ the build, but we don't include them _in_ the build:

 http://gendl.blogspot.com/ (slightly relevant in this regard)

To accommodate those customers who may want to load additional Quicklisp
libraries on top of our system, we do make it easy for them to load
Quicklisp once they have our system up and running. But by default this
will be exactly the Quicklisp version with which the current build was
built, so we don't have to concern ourselves with providing compatible
versions of third-party libraries for each build that we ship out, or with
the risk of a user loading a newer and incompatible version of an
additional library or one which they already have loaded. Quicklisp does
that for us.
