OpenSolaris plus gnu/gnome

OpenSolaris launched in blogs.sun.com. And from OpenSolaris.org, you could see that you will be able build OpenSolaris with gcc tools in future.

I am not an OS expert :), but personally, I think someone may have
interests to build an OpenSolaris distribution with OpenSolaris kernel
and admin tools plus gnu software stack, including gnu libc (is it
possible?) ,gnu shell utilities, Xorg (does not belong to Gnu; Solaris 10 x64 are using xorg),
Gnome desktop environment (Solaris 10 already bundled Gnome 2.6).
Actually, you could download many opensource softwares from
http://www.sunfreeware.com.

At last, welcome to Internationalization and Localization community for OpenSolaris!
