[Bf-committers] Blender and Collada support. Does it matter?

At Siggraph I sat down for a meeting with Khronos, and they started
with "what can we do for Blender". I mentioned two main issues; 1)
OpenGL compliancy (Intel especially) to make vendors give better
information what kind of options to avoid or how to bypass it; 2)
Collada support, which still fails to deliver up to expectations for
(more advanced) animation im/export.
For Collada, Khronos would "look into it". They do seem to have some
funding opportunities, but it's not common to pay for integration
really. I'll keep in touch with them on it.
The main point however; as for most aspects in an open de-centralized
project like Blender, is that we have to define & involve the
stakeholders for features well. The responsibility of BF or (BI)
should be as limited as possible here. It would be much more
interesting - and beneficial for everyone - if our Collada project at
least gets involvement from people who directly benefit from it.
In all our past Collada efforts, the developers working on it did this
out of general interest or as GSoC project, but they were not the
actual users nor depended on it for productions.
I really would prefer to not do this via donations or fund raisers,
but to locate a couple of companies with development departments who
can practically help us out here. Would you be able to help with that?
It can be quite simple even, just companies scratching their itches...
what would hold them back to help us, or how can we get them involved?
