That's the method I need, although it is not exposed externally. I 
can call it from inside the simulator, not via HTTP. Correct me if I 
am wrong.

Yes, the picture shows media on a prim. It's pure PHP+SQL+jQuery. It 
gots the .jp2. There should be no difficulty building an IAR (except 
headache).

My ability to code in C# is low and I never had a look to the 
sources, so this one will be tough. Let's suppose I succeed.

ATM, the delivery is trigerred by JavaScript inside the web page. It 
can be replaced by a script doing HTTP. I get the region name 
(X-SecondLife-Region) which I should be able to translate to UUID 
using the database or calling GridService. The user UUID is trivial.

The selection goes as low as a single texture. On-the-fly is 
mandatory. Create the folder structure, generate the XML and tar.

Ah! I see you have documented a new batch of services. More API to 
play with :))

I already get the serverURI from the 'regions' table.

You made my roadmap. However, if I manage to call 
UpdateClientWithLoadedNodes, I can skip the IAR step.

Yes, using InventoryService is cleaner than inserting a row in the 
table. However, the items will not be available until relog.

You just saved me a lot of work.

Thanks so much.
