For the record, Sourcefire has put no proprietary mods into Snort at this
time, the version running on our sensors is the exact same version that you
can download for free at snort.org.  That's why the software has been
improving so much lately (from a features and stability standpoint), we need
it to be there for our commercial users and you get the benefits of that
work.  All the proprietary stuff that we do wraps around Snort and interacts
with it, but doesn't link directly into it (and therefore doesn't need to be
GPL'd itself).

Then you get to code the "everything else" that the commercial vendors
provide.  If you modify Snort in any way, the mods that you make should be
available upon request whether you're selling it as a service or a product,
I think this loophole is closed in the latest version of the GPL.
