[Rock-dev] LAN communication and WebService

Rock components are capable of using corba to communicate, thus they can 
run on different machines in a network.

All you need is a naming service, Rock can use the corba naming service 
on a "master" machine:
http://rock-robotics.org/master/documentation/runtime/setup.html

Or use avahi as naming service:

Alex already told you about our plans. In case you don't want to wait, 
there is a "not so nice" but working solution using ruby 
websocket-eventmachine-server on the rock side and html5 websockets in a 
browser.

But all the marshalling and parsing has to be defined manually in ruby 
and Javascript. The usability depends on the task you want to solve.
I can provide you some more information in case this is an option


Another Idea (untested and not well invertigated) is to use the rock-ros 
bridge 
(http://www.rock-robotics.org/master/documentation/ros/index.html) and 
ROS for android (http://wiki.ros.org/android).

But i have no idea whether ROS for android is compatible to the normal 
ROS used by the bridge.


Best, Steffen
