This looks like an important goal for the relicensing effort to me which I 
hadnt thought of initially.

It hasnt been tried afaict, but it looks even more realistic when we achieve 
the universal binary build which should simplify distribution logistics 
substantially.

Would this then be the 'lazy lawyer' requirement?

- "licenses published with LinuxCNC must be compatible with all dependent 
packages 'prima facie', that is without studying further license arrangements 
not specifically spelled out in the published licenses per se"

it would translate into something like this statement:

"The license(s) applicable to the LinuxCNC code is/are here: <link(s)>"
"The dependent package licenses are here: <links>"
"According to compatibility matrix entries <links>, these are compatible."
