(Fernando, you sent your answer both on my personnal address and on ipython
list, but I only received it from my address. Is it normal ? My mailer does
not remove any message, even if it is cross-posted...)

I will update my document if I have new ideas or needs ;o)

We do not have public page, but Ican make a little paper for you (I already
did for the Pyro project page).

I didn't post it, but I have a little piece of code to overload
IPython.iplib.InteractiveShell.runcode() method. In this method, I just
catch our PyMAD project exceptions, and print a message instead of the
I also catch a Pyro exception. I would like to be able here to get the code
which lead to the error, because I would like to make an automatic ribind
on the pyro object which as failed.

Yes, I want to avoid the user to delete some our Pyro remote object proxies,
through the del operator. The idea is to give ipython a list of objects
which can't be deleted.
But I understand it is not very easy to do. Let it at the bottom of your
todo list !
