Hm, I share Pd patches with people on and off this list for years now, it never was a big problem to use patches made by someone else, so I don't see where the problem is? Is it installing externals?
its knowing which externals to use, in the nameclash sense, as well as in the nondescript error in the scroll like: expected float but got '', etc. practically impossible to even tell which object it is talking about...
