Re: [ecf-dev] Riena Webinar

Hi Christian,

I do request that you not refer to ECF remote services *versus* Riena 
Remote Services.  In my view they are focused on different things:

Riena:  provide a full remote services implementation with features like 
transparency, advance security, others

ECF remote services:  provide transport independent abstraction(s) for 
remote services...and multiple implementations:  e.g. r-OSGi, ECF 
generic, XMPP, JMS, others (hopefully Riena).

Given this, I think it's incorrect to refer to them as one versus 
another.  By analogy, r-OSGi is also an remote services implementation, 
and there is absolutely no conflict with ECF remote services API 
(witness the r-OSGi provider, which Jan created very rapidly).

As we discussed at the summit, I think the best arrangement would be to 
have a Riena-based provider that can be accessed via the ECF remote 
services API...and *if* Riena has unique features (e.g. security) that 
imply/find additions, bugs, or changes to the ECF remote services API 
then these can/will be happily added in the ECF 3.0 release cycle or 
beyond.  I've started such a Riena-based remote services provider, but 
have not completed it yet due to the fact that Riena impl has been 
rightfully changing rapidly, and I/we've been consumed with other 
things.  But I invite the Riena committers and/or contributors to work 
with us on this provider (as you are obviously the ones with current 
knowledge of Riena's internal structure) and add/contribute/improve the 
ECF remote services API.

*If*, in fact, Riena *is* attempting to provide just such a transport 
independent abstraction/API as well, then this is a direct conflict with 
ECF remote services and these efforts should be consolidated rather than 
having two projects doing the same thing (one mature and the other in 
incubation, and one based upon multiple implementations and the other 
based upon one implemenation).  In my view, anything else is extremely 
confusing for both communities.

P.S.  I did watch the video...nice job.
