Hi Justin,
Yes, I saw the inventory/Libraries.xml but haven't tested it yet :)
I'll do that in a few minutes :)
Thanks again for you great job ... And if you allow me, i'll post an
entry in the OpenSimulator Wiki about that ...
I'll also try to contact melanie about JP2 ...
Thanks again,
Happy new year,
Ursula.
