What subject would you like to give on the server meeting ?
Please provide any technical subject you can give a session on the Server Forum.
Please add relevant information like the customer you are using it, relevant links etc.
Please note it can also be a framework that interest you and did some research on it and you think can interest the forum.

I suggest that people reply with +1 to topics that interest them, so we'll there's actually an audience.
I have two suggestions, both in terms of high level architecture, not technical details, unless people want the dirt and gritty.
Erlang - The point of the lecture won't be to learn a new language, but a high level introduction to a programming paradigm that is different from the popular languages (ruby, java, scala etc.) and yet is oriented to the server side world. Erlang is a mature language that has been around for ~20 years. It was developed in Ericsson for driving their huge telephone switches, and was open-sourced 10 years ago. Its focus is on creating fault tolerant distributed multi core systems.
Btw, if anyone is interested I have the book written by Erlang's creator which I'd be happy to share.
REST - understanding the architecture behind rest, in order to build truely restful applications (not just pretty urls). the lecture may or may not give an overview of current technologies, depending on the wishes of the audience.
I think that Erlang might be too remote for most developers. I mean, it IS interesting, but perhaps not for this crowd, we usually go for something sexier and less theoretical. Are there real-world Erlang use cases we can talk about?
Does it(sorry...) run on top of JVM?
REST is good, although I think we might have trouble both describing what is rest and giving a more-than-helloworld demo in time allocated.
Judging from the lack of votes, it indeed seems this is not attractive.
Erlang is not a theoretical or toy language developed by someone in his home. It was developed by Ericsson to drive their phone switches. I think Ericsson has ~100 people working with Erlang
About real world use cases:
* ericsson's huge phone switches (850K LOC in erlang)
* facebook's chat system (scales to 70 million users)
* amazon's simpledb
* wings3d - a 3d modeler
* yaws - a web server written in erlang which scales much better than apache (see http://www.sics.se/~joe/apachevsyaws.html)
* ejabberd - a jabber server, used by jabber.org (replacing their original c based server)
Erlang is a managed scripted language, so it runs inside a VM, but not the JVM. Erlang was designed to allow creation of scalable, fault tolerant applications, these design goals drove its syntax and features. Its VM takes advantage of all of them. Since JVM was not written for Erlang, it will not drive Erlang applications as well (btw, Erlang is cross platform)
Java7, ESB, DM Server
Java 7 has lots of new features and APIs, even without closures:
Concurrency package(fork-join especially), Invokedynamic and the whole scripting language deal, G1 Garbage collection, JMX 2.0 & Web services, XQuery API, NIO2, ...
see: http://tech.puredanger.com/java7
Battle of ESB implementations - ServiceMix, MuleESB, Spring Integration, Apache Camel/Synapse... see list here: http://en.wikipedia.org/wiki/Comparison_of_business_integration_software
I think there are pretty mature implementations out there, and they can be used not ony for heavy lifting - interesting both architecturally/design-wise and technologically. see: http://today.java.net/pub/a/today/2007/07/31/exploring-esb-patterns-with...
SpringSource dm Server - Mechanics and status
The community seems to have a slow pick up, this might be a good topic and there is enough material on it from Spring blogs... fuul list here: http://www.springsource.com/products/suite/dmserver
Zvika is right, I would love to hear about ESB and OSGi more.
I can show some work we have recently done with Pentaho (ETL, reporting & OLAP) and with Mural (match-engine).
If there is an interest in ESB, I can prepare a session on Enterprise integration patterns (EIP): http://activemq.apache.org/camel/enterprise-integration-patterns.html
