Forum OpenACS Q&A: Re: GPL and the use of GPLed Code in Commercial Products

Frank, I don't see why whether you save custom code in the filesystem or in the RDBMS has any necessary relationship with run-time extensibility, nor with preventing CVS upgrades from overwriting custom content. These are orthogonal issues AFAICT.

Your Project Open stuff may and probably does have real and necessary technical design differences from other OpenACS packages, but I don't think that's the reason.
