This software also supports the EyeOne Display. If they are also using the
vendors SDK to support the i1 then the software can not be legally GPL.
Section 3.2(b) of the EyeOne and Huey SDK license agreement has a condition
that would prevent it from being used in GPL software since this section of
the license agreement requires any software that uses the SDK to alter their
license in a way that makes it incompatible with any of the existing OSS
licenses including GPL. The alteration requires anyone wishing to
redistribute or alter the software to get permission from
GreytagMacbeth/X-Rite. I have contacted the web master and asked for a copy
of the source code. But like Graeme I am not too optimistic that the meter
interface code will be of any use.
One of the interesting things is that this software was originally written to
support a DYI color meter that you can down load the plans for from the web
site. They claim that it costs 20 to 30 Euros for parts to build as a one
off and is a better instrument than the Spider2. Kind of gives you an idea
how inexpensive these meters are to build and how big these vendors margins
are since building stuff like this one off is significantly more expensive
than mass producing the same type of device.
