Hi Cyrille,
i have to look a the dyn object, i'm sure i'll find lot's of interesting idea for the future developement of [pmpd].
Although there has been some development pause for the dyn library since the first presentation at the pd convention i've been working on it lately and plan to do so for the next future. It is supposed to be a general API for object management in PD, so maybe you would like to use that instead of using code from the dyn~ object. One of the features that i'd like to introduce shortly is the ability to load patches in a click-free manner, made possible by the low-priority callbacks now present in the devel branch (hopefully also in the stable version soon....)
best greetings, Thomas
