Maybe I should be a little bit more verbose in the FAQ......
Could someone please give me a link to a thread in the mailing-list archives which lead to disabling IIOP in ORBit-stable-0-5 per default ?

The latest INS spec changed the names from iioploc:// and iiop:// to corbaloc:// corbaname:// because they don't want to have the name of the protocol in the URL. In the future there might be other protocols which requires different parameters to go into a URL. Having "iiop" as the protocol
identifier would make no sense if another protocol than IIOP is used.

But it is the official resolution of the bootstrapping problem, with which CORBA is struggeling quite a while now. If you have a look to the preliminary CORBA 2.4 spec you can see that the INS spec is going to be integrated into CORBA 2.4 (chapter 4.5.3: Configuring Initial Service References). I
think the corbaloc/corbaname URLs are intended to be used only for the first reference. If you start your client which connects to a CORBA NameService you don't have to think about any proprietary ways to get its IOR ( reading from file, environment variable, retrieving from X window properties ).
If you know the name of the server on which the NameSerice is running it should be enough to start your client with the following command line:

myclient -ORBInitRef NameService=corbaloc://nshost/NameService

The client application can use just the call to resolve_initial_references("NameService"); to get a valid object reference to the Naming Service and from then everything works as before....
