Just to be clear, the code in the main GDM branch (trunk) is
completely new and probably does not include the code you are thinking
of.

>From what I can gather from what you have revealed about the Sun Ray
system it sounds like there is a great deal of overlap with some of
the things we currently have and plan to have in the upstream open
platform.  I think it would be advantageous for everyone to be working
toward a common goal.  In my opinion, it is very hard for this to
happen until you publish your code with a GPL compatible license.

I was pleased to hear you are already considering this.

Let's get that done and then talk about the next steps.
