I understand Photocomix I appreciate the kind response,
Another possible way to share for Linux could be Virtual Box similar to Samj's post
http://gimpchat.com/viewtopic.php?f=7&t=8824&hilit=virtual+box with all the dependencies installed already(Keeping distro size small enough to fit on a dvd around 4gb.used and allow alittle more free space on virtual hardrive to allow room for remastersys to compile it for an iso.) .
*remastersys wiki link* Of course just exporting a copy of a linux distro with remastersys without even using virtual box is possible and probably smarter.
other art programs are easy enough to add using PPA's and Repository's and deb packages.
Actually a custom community created distro containing the wonderful contributions from everyone on gimpchat would be pretty cool,if possible all the artist,photographers etc. here could contribute backgrounds, slash screens, compiles, plugins, etc. to it.

Of course file size could be large when dealing with distros.
