I'm using leJOS to extend my Lego MachineCloud project, http://brickinthecloud.com/
. As you can see by the blog, I've had some success with NXT, though the Wifi block I used was quite limited (it didn't support HTTPS for example).
With the new much more powerful EV3, I plan to continue the project and take it San Francisco next week to demonstrate it at the huge Dreamforce event! I will be demonstrating the robot responding to streaming events sent from the Salesforce cloud platform applications and using their Chatter (like Twitter but for Salesforce users) application to communicate via Mobile.
The robot itself will likely be one of the standard ones, I've not a lot of time to build my own robot and write this code! Really enjoying it so far, when I post on my blog and I'll cross post here. If you want to follow me on twitter there is a Twitter account also called brickinthecloud.
Thanks and once again thanks to the leJOS devs for making this all possible, will be sure to credit your great efforts!
P.S. Are any the leJOS devs on Twitter?
