Hello out there,
just my 2 cents on the recent development and my opinion on the future
development.
Bahadir, I completely understand your arguments and can agree on the
various trade-offs that arise with business models around open source. I
have just a few points, that I consider relevant:
1. an important fact in _your_ consideration should be, that codezero
until now failed to build a broader community. With that I mean
developers outside B-Labs, that significantly contributed. Having a look
on the archive of this mailing list, one finds when there was any mail,
it was either "what is going on with codezero" or build issues. The
reason for this may be manyfold and hard to identify, but the project
source, build and docuementation is well shaped.
2. Codezero is in a shape it can actually be used in production. As I
understand your currently closed development, the main novelties are in
the userland, right?
3. With the decision to change licensing of the sources from now on, it
might still be possible to hope for a community to form and develop the
open branch, while the closed branch is deverging. GPL is not very
friendly to easily get this stuff together (except going back open source).
Summarizing, you may think about splitting codezero up in the open L4
kernel part and closed userspace stuff. With the kernel you can hope to
gain attraction from developers, that are really willing to bring
codezero forward, while a business model around the userland, boards,
configurations, support might work out for you.
It will be hard to find the exact part that stays open and which is
close. Having closed stuff in the kernel in your house, makes sync'ing
stuff hard in case there is a developer boost coming up. Nevertheless
you can bring stuff to the open source version at any time.
I would suggest, to try to establish a simple open source project
management such as Trac with the current codezero repository and see
what happens. The current status should be sufficient to attract people,
maybe try to advertise it. Meanwhile you can try to build your business
model with clear boundaries between open and closed source and bring
your stuff in, participate in the open source project and try to make
money out of your really nice novel stuff.
Bye,
Stefan
