Hi Esteban, You may want to check some proxy implementations I did. You can check Ghost proxies in my PhD thesis: http://rmod.lille.inria.fr/archives/phd/PhD -2012-Martinez-Peck.pdf and here: https://hal.inria.fr/hal-00877757/PDF/main.pdf
One of the things I did was to be able to enable (could even be done dynamically) debugging capabilities to proxies..that is...proxies would understand theirself all necessary methods for inspecting/debugging/printing/exploring them without actually intercepting the message. You can read about that in the above links. As a quick prototype.... you way want to create a subclass of ProtoObject or directly add those messages to the Glorp proxy. Also...AFAIK, Camille Teruel was doing some stuff with Ghost Proxies, so he might have the latest version available somewhere. In anycase, my original code was in: http://ss3.gemstone.com/ss/Ghost but saw there is also: http://smalltalkhub.com/#!/~CAR/Ghost/ which may be newer.
