Exactly my point. There's no clear advantage in doing this.

Ok, but I was not questioning about the tools used to allow external
development. My concerns are on the opportunity on changing the maintining

Indeed, but still a supervision from the core development team is required.
Just like today: my experience with this mailing list is that if somebody
has a really useful patch to submit either for the code or for the docs,
he/she just inform of the availability of the patch to the fine people at
Ericsson thourgh the list. I bet that after a close inspection, valuing the
pro and cons of the patch, they'll schedule it for an upcoming release. I
don't see how automating a small part of this process can simplify the life
of a developer.
If I remember well, I know of a user contributed patch solving a real
problem; this was acknowledge by the Erlang team, but was rewritten because
it contained bugs/constraints/whatever that would impact on existing code.
They'll find problems because is their job to run regression testing among
the other tests.
My personal experience with "truly" open source project is that the part
time maintainer has no time/equipment to test it all, so first he just
release the stuff, and then lets the bazaar to sort it out.

My point is: we (Erlang professional users) should avoid the generation of
different Erlang flavors, based on experiments or otherwise. I think that
one of the often overlooked task of the Erlang team is keeping it up to date
on several platforms, evaluating the risks and the benefits of each single
patch, giving a warranty that no existing, deployed code will break.
They (Erlang team) have a formal procedure of doing this; my experience with
open source enthusiast is that sometime patches and upgrades are done in a
"spray and pray" mood.
