Hi Krzysztof,
i had a longer look at your rabin~ code and i found that it uses the same
approach that i had in mind.
However, my intention was not to have something identical to Max-poly~ but a
means to dynamically create complicated patches (for example with Python

This is true and i'll not implement it at this time. I want to stay
compatible with pd version changes.

I use proxy input and output objects which are connected to the objects
dynamically created inside the external.

I won't support editing as it would disturb the object database of my
external. However, there's a possibility to view a patch.

I'm sorry... i guess not....

 For the time being, the main stopping factor is Pd's

That's not a real problem for me... i can get along with separate inlets and

I'll publish a first version of dyn~ as soon as i have the time to do it....
(there's one drawback with it... my external needs a tiny patch to pd
exposing the "newest" pointer... i already patched cvs devel_0_36 in this
