[Opensim-dev] Questions about hypergrid (eventually)

[Kurt Pudniks]

Hi Mike, all,

Love the idea of writing an article about opensim.  I support your
enthusiasm!

The source code will show you line by line how things are done.  Question
is:  how does each grid modify their base code to adapt to their users?
This tends to be somewhat commercial in confidence ;)  and therein lies the
big political problem re evolving opensim 2.0 right now...

I'm aiming to learn some opensim (C#) for my own understanding of what is
possible.  Feel free to email me directly and we can chat more ie I might
read (perhaps even explain at times! :) some source code for you as a
research assistant of sorts...

Thanks,
Kurt.
