using node as server
using socket.io for web sockets
40 mins to migrate to a server and get some basic messages passing around.
an hour to get notes moving
40 mins to get caching going

Simple Part: 
- Use last week's assignment of Sticky notes and create a Collaborative 
sticky notes app 
- Multiple browser instances of the application will show the same sticky 
notes. Changes in one instance reflects the change in all other browser 
instances. Make use of WebSocket to achieve this. 
- For instance let's say user1 and user2 access the sticky notes website. 
User1 creates a sticky note. The user2 can instantly see it in her browser 
(without doing anything like refreshing the page). 
  Now if user2 enters any text into the sticky, user1 can see it 
immidiately, and vice versa. 
- If user closes the browser, disconnects internet and open the browser 
again at a later point of time to access the site (offline), she can view 
the last updated sticky notes and work with it. (Use AppCache to achieve 
this) 
Complex part: (Optional. if you complete simple part and want to take up 
something more challenging) 
- The user can set time based reminder in sticky notes. When the time is 
reached, the sticky note vibrates and creates an alarm noise. A stop button 
stops the sound and vibration. A snooze button makes the alarm ring again 
after 10 minutes. 
- Show animation when notes are created and deleted. Effect of scaling up 
from zero height and width to regular sticky size on creation of a sticky 
and fading away when a sticky is deleted. 
We would highly recommend that we all do the Complex part of this app too. 
If we can complete both the simple and complex parts here, it will give us 
a lot of exposure to the main features of HTML5. 
Please post in your questions and recommended solutions about the app and 
HTML5, here.
