admittedly I didn't look at dynamic patching for a long time.
I remember that I searched for infos on best practices etc. but didn't find anything helpful back then.
so curious as I am I still wonder what would be a good way to approach this.
João's [jmmmp/dacm~] is nice but 'harmless' in this respect.
