"Freetown" in that remark makes no sense to me, mashburn. Neither does the rest of your first sentence. Perhaps a member will come up with a reasonable idea if you can explain more clearly what you were discussing with your colleague.
Looking at the phrasing, the only completely unsupported guess I can offer is that they name or nickname versions of software alphabetically after towns, so version F is nicknamed Freetown. Again, this is just a guess based on the phrasing as presented.
