3 points:
* OBS is completely GPL
* so... a setup of obs.maemo.org is encouraged (I intend to setup a local OBS here)
* Suse/Novell are providing a very valuable and free service to the OSS
community. There is zero tie-in just a 165 strong server farm.

Novell's "confusion" is important but, IMHO, not relevant here.

I didn't realise the page needed a login; but really... "FAIL". Maybe you could
look a _little_ deeper.

The OBS guys are aware that their ties to Suse/Novell make it sound like a
builder for a single distro. However it isn't.

It builds for:
* Debian
* openSUSE
* Fedora
* CentOS
* Mandriva
* Ubuntu
and now:
* Mer
and lots more...

* armv5el
* i586
* ia64
* ppc
* ppc64
* x86_64

and it builds *all* the packages (as in the entire distro) for the offical SUSE

OBS is more a VM/chroot manger that runs each distro's own packaging and build
software. It supports Xen/KVM/Qemu/chroot.

So for Debian it does an apt-get build-essential, pulls all the build-depends
and then runs dpkg-buildpkg. Similarly for other distros.

Oh, it also provides a working local buildservice that doesn't need scratchbox

Mmm "decision by language".

As can OBS.

Agree. Would you agree that it's good to find a mature solution with a solid and
funded team behind it then?

As I said, Suse eat their own dogfood - OBS is used to build the released SUSE

IMNSHO the SoC project is vapourware and/or a NIH toy by comparison :)

I admit I am biased - I thought Mer needed something to use as a builder and
when I found OBS met our needs I began using it. Mer 0.13 will hopefully come
from OBS and I'm now running Qt4.5 from OBS on Mer on my N800.
