[Zope] adding a custom attribute to a mybrain object

[Huron]

Hi,

        I'd like to sort of add some metadata to a returned mybrain before it gets
handed to the skin for display.
        I've been thinking that it could be possible to just do a 'setattr' on my
mybrain ... but it's not working since the brain is a very special object
relatively to it's attributes (from what I understand browsing the code).
        It there a way to do that properly ?

Thanks in advance,
