Hello, guys! My name is Eugene Nazarchuk, I’m a postgraduate student of National Research University of Information Technology, Mechanics and Optics in Saint-Petersburg, Russia. My colleague, Dmitry Zamula (club.brantner@gmail.com) has already written a letter to Mr. Jay Balunas about the project of mobile document collaboration app.
I have about a year experience in enterprise software development using Java stack, Node.js, Javascript and Coffescript. Dmitry has 2 year of experience in enterprise development (also java) and works on his own app for Phonegap platforms. We are interested in project of mobile document collaboration app because it uses advanced mobile technologies. It’s a good opportunity to get a lot of experience in this area.
Today we’ve spent some time developing a prototype of that application. Now it has a functionality of concurrent editing of a document by several clients and some base document markup. All communication with server goes through web sockets. Client is implemented using Phonegap. Prototype is pretty raw but it helped us to pinpoint main difficult parts of the system. First of all is lack of support of websockets in android (and integration of existing websocket libraries with Phonegaps API). Also the task of markup the text is not so easy, because the majority of WYSIWYG editors aren’t adapted for mobile devices. In particular we faced the problem of positioning the caret while other clients are concurrently modifying the document.
In current prototype we intentionally used not very optimal algorithm for transferring document changes between clients, because we just wanted to roughly estimate the whole scope of work.
In the project description there is a mention of Aerogear framework. As far as we understand it does not support websockets right now. So we have a question: will this functionality be implemented soon, so it can be integrated in the project?
We are glad to answer any questions about us or the prototype. We can expand its functionality, if necessary.
Best regards,
Eugene Nazarchuk (megistion@gmail.com)

Prototype:
mobile client - https://github.com/Brantner/mdc
server - https://github.com/Brantner/mdc-server
the server is deployed here - http://mdc-brantner.rhcloud.com
We cannot provide a compiled version of the client, because it doesn’t work for android right now (lack of native websocket support) and must be compiled for iOS using UUID of the particular device it will be used on.
