[PD-dev] writing exploits in Pd (Re: [PD] [file])

What a fun thread.

It does raise the old trust issue (I prefer that word
to "security")

[shell] was always the obvious tool for mischief.

In the end Pd is a programming language - caveat emptor

Sandboxing has already been mentioned. It's not so easy to
make cross platform, but a chrooted or cgroups constrained
(semi-containerised) install should be possible for linux.
Maybe that could be an install choice, for a "hardened Pd".

Careful code signing and review for Deken is probably a better
future, and Pd community is small enough to manage that I think.
