Interesting. I actually have access to a SpectroCam (Serial, not USB),
but haven't felt it possible/worthwhile to support it in my software.
If the drivers really were available as GPL (even if there was some work
to get it going), and anyone was interested in actually using it
(ie. that it wouldn't be an academic exercise), then it might be

In Argyll I have a kind of abstract instrument layer, and the drivers
are implemented underneath that. Every instrument usually causes some
expansion of the abstract layer, but it's generally not too hard
to add support, if the information is available.
I'd love to have support for the i1 and i0, but I'm certainly
not going to fork out the A$6K (or whatever it is) for an
i0 and i1, without firm knowledge that the technical information,
or compatibly licences driver code, is available.

Xrite were pretty good in the past, with their serial port based instruments,
but I'm not so sure that things like the "Pulse" or "MonarcoOPTIX"
will have accessible interfaces. Presumably the DTP45 might be a variation
on the DTP41, and the DTP70 might have a high level interface, but
it hasn't been worth pursuing, since I don't know anyone who's
got one, and would let me work with it.
In the case of GMB and Xrite, they both have their own software,
and this provides incentive to close or frustrate access to many devices.

If you put yourself in their shoes, you can understand that they will
do the cost/benefit equation (as they see it). Who pays for the
development instruments becomes an issue. Without the instrument
company seeing enough benefit to provide some loaner/free
instruments, or a moneyed supporter of OSS willing to buy them,
things aren't going to go anywhere.

Hmm. The SpectroCam I've played with did emission as well.
