Questions
Introduction
So, what are we going to talk about?
We are going to talk about the WebLab-Deusto project
It aims to provide software for the Remote Labs developers, by
providing an experiment-agnostic framework
This is more or less the idea of the talk:
First, brief analysis of the requirements of a Remote Lab
We will focus in several aspects that are interesting for Remote
Labs developers
Then, show WebLab-Deusto approach
Finally, discuss :-)

Let us work on that
Right now, we use SOAP, but we have almost finished
XML-RPC and JSON
We know that Doc needs speed
so we’ll support sockets through Flash soon
if Flash is available
no firewall
Anyway, doc, you shouldn’t need to know it!
Software changes a lot, and optimizations in the underlying
