btw (if i havent asked yet) - do u have a place describing all things that happen to some user's object/class once given into SA's arms? e.g. all the attributes that grow on the instances (and has to be avoided by user), replacement of __init__, all the descriptors for attributes, etc? i can prepare something like half a page on this theme, but u'll have to fill up as i surely have no much idea of which is what/why.
