Distribute processing with omniorb2

There is no need to run omniNames on the client machine as well. You only need 
to have omniNames running on one machine on your network. 

When you run omniNames, it outputs a stringified IOR. You should
copy the IOR (including the IOR: prefix), and add it as the (string or REG_SZ)
value NAMESERVICE under the key HKEY_LOCAL_MACHINE\SOFTWARE\ORL\omniORB\2.0
Use the tool REGEDT32.EXE (on NT 3.5) or REGEDIT.EXE (on NT 4) to do this.
You must add the IOR to the registry of every machine upon which you want to 
run omniORB applications. When you have done this, you can run nameclt, eg3, 
etc. 
Note that you can use a configuration file instead of the registry. 

The steps for configuring the Naming Service on Win32 platforms are documented
in README.win32 . It is also documented in the omniORB User's Guide 
("Setting Up Your Environment") in chapter 1. The documentation on nameclt is 
in the omniORB utilities guide ( utilities.{pdf,ps} ).
Documentation on the examples is in chapter 2 of the omniORB User's Guide.
