Interoperability of Orbit2

[Munaut Sylvain <tnt 246tNt com>]

Hello

I'd like to use a Orbit2 server on a Linux machine with a MacOSX client 
using Objective C implementation of corba (ADORB). ADORB use IIOP 1.0 or 
1.1.
It works fine ( or almost, some times it just hangs ... ) with Orbit1. 
But not with Orbit2. Is'nt it backward compatible with IIOP 1.1 ?

I haven't found many information about it on the net

Tanx
