Is Ubuntu interested in projects like this?
If so, here's an idea.
============
Step beyond hardware licensing
of conventional accessories, attachments, devices, etc. (don't drop it - keep it - but build on it)
Consider Partnerships , and
partnerships with new hardware that is totally new - hasn't reached consumer market yet.
Whether its providing a software platform, assisting with drivers, interfacing, advanced applications programs for end users, or
drumming up some sponsorship, advertising to Ubuntu users for donations (or any other form of support) - there are bound to be some ways to get involved.
This might involve teaming up with Debian and its other variants.
Solicit approaches from (potential) hardware manufacturers on the Ubuntu web site. They maybe inventors, new startups, or established manufacturers with a new product line.
Ubuntu could "Help" new products come into the world.
The "attitude" of Ubuntu may be an advantage in this activity.
Additional idea - sometime later (don't vote on the basis of this - it's just a thought for the future.)
Maybe raise some funds to assist with projects.
No-strings attached donations.
Help young projects to;
Avoid loans.
Avoid angel investors with clawed feet.
Work for the greater good than just pure profit.
