Regarding distribution of the official AdobeRGB, Adobe does require a license.
It also isn't clear what Adobe would consider an allowable name for an
"Adobe-like" open source profile: "Companies who are not Adobe
licensees but who claim to have technology that is compatible with
Adobe RGB (1998) ICC profile software may claim, if true, that their
products are "compatible with the Adobe RGB (1998) ICC profile" as
long as nothing in the circumstances would create consumer confusion."

This whole issue of what to call open source versions of popular
copyrighted profiles is vexing. Rawtherapee has resorted to Large,
Medium, and Small for ProPhotoRGB, AdobeRGB, and sRGB!

The Argyllcms ClayRGB1998.icm profile that you get when you install
Argyllcms is an open source/public domain version of AdobeRGB.
I'm writing up a little stand-alone c program that generates proper
RGB V4 icc working space profiles. The bare-bones program works. The
next step is to add in descriptions and copyright information. I'm
happy to share the code if anyone is interested.
