new ideas ever welcome

i like this can be usefull, the problem is how mcuh espace you need to
redistribute all sources we need (not only gnap-core srcs, i mean
extensions srcs too)

i dont understand it well

this will be one of the biggest features so as you know is hard.

you mean gnap doc or catalyst doc?

ever welcome :)

i think that is hard, you dont need root only for catalyst, other GNAP
operations need to be root.

yes, what about your google-code testing?

you are right, but first we need and updated tree

i prefer to keep bash
