Well I havent' found any document on how the IDs (like 
1e3ad60;uno[0];18b8;85f8da80603b478cb08cd837553b7f6d) are defined...so 
I've used Windows GUID to identify my objects instances.

soffice is waiting also for something because the document is opened 
when I kill my application !

my application is a single thread process, after the protocol handcheck, 
I send a request a read answers until I get my own threadID back, 
something like :

   while (get_reply->thread_id != my_thread_id) process_server_request();

from my point of view, soffice and my application are both waiting for 
something from the other side.

it's probably something wrong in my URP implementation, but what I can't 
understand is that the same client work just fine on a remote office, 
and that a second instance of my client work also just fine on a local 
host. How can my code be wrong only on the first connexion to a local 
office ?!

BTW I agree with you, the best way to understand what's going on is to 
look at the server side, but I'm a Delphi developper, debugging 
soffice.bin is an hard task for me :)

I've made a protocol sniffer to trace Python to Office exchange...it 
does a lot of unnecessary things (XTypeProvider, XElementAccess, 
XNameAccess, XUnoTunnel.getSomething, etc...) but I can't figure what is 
missing/wrong in my code to just open a private stream.
