HTML 5 or Java / socket application, proof of concept

Budget $30 - $250 USD
Bids 8
Average Bid $185

this is a proof of concept application, for a distributed information/notification application, if we can test successfully will go for a full version.

we currently have it based on windows and sockets, What we want to do is convert the remote end to work as a platform independent application.

We are strongly interested in using very standard up to date and flexible technology, would like to see it on html5 and java-script however could consider others like java if you convince us of their pros.

Description of the functionality:

On this system we need to keep information on the current state of a group of users, and be able to send them simple short pop messages.

As for states, for easiness think each user can be in 'green', 'yellow' or 'red' .

Users will open a browser and using normal html5 and javascript, will log in and authenticate (database authentication would be a plus but don't want to raise costs at this point just jet)

As users log in, they will be able to see a list with all other users logged in.

Function 1: send_msg
We need to be able to send messages to each logged user with a command line to the web server. i.e. [url removed, login to view]?hello_user1

Function 2: change_state
We need to change the state to each logged user, with a command line to the webserver. i.e. [url removed, login to view]?red

Function 3: logout_user
We need to logout an user

when a message arrives at an user we want to have it on the main screen, with the remitent (in this case the admin user), but also want to do a desktop notification in case the browser is minimized or does not have focus. (a beep will also be desirable)

(for ideas on desktop notification check : [url removed, login to view], or [url removed, login to view])

remember, keep it low and simple, if we sell the concept further stages will enrich this with all improvements and goodies to create the full product. which could include in you maintaining the code product

On ANOTHER project, we need the same but on an Ipad or Iphone and on Android, if you have experience and think can work on that, PM me to invite you when the time comes.

Sorry, no money upfront, check our feedback, best we can do is to have a milestone when you can deliver something working.
