Thanks to both of you. I have created proxy objects and they work.
GridFlow 0.6.2 will include the Ruby<->PureData bridge I've written.
However it crashes after a while due to memory corruption, which I don't
have while running with the other bridge or running standalone.

Also I don't know how to correctly tell to PureData that the object should
be greyed out and disabled. What I do in the Ruby/C++ part is I raise an
exception in the constructor. I catch that exception in the bridge and I
