Subject Re: Prioritize Modernizing The Specification

Yes, that's correct, there's still an IIOP exporter, although it doesn't 
support secure sockets, so it's probably best used locally.

Interestingly, when I was looking at the OSGi remote spec, it needs 
existing protocols in common at each endpoint.  This is a little 
different than Jini / River, where the protocol is part of the proxy, so 
the client needn't know anything about that.   I'm not looking at 
comparing approaches, or determining which is better, obviously the OSGi 
communication protocols could be used in a Jini / River proxy 

At this time at least, services can be program language agnostic, but 
clients require the jvm, I guess it might be possible to do something on 
Microsofts CLR or Android as well.
