Shoutbox

In class me and my friends often send messages to eachothers mobile phone using bluetooth during class,
However a few downsides are that some mobiles can only send calendar messages, some don't show the sender, it's pretty slow, etc.
So I decided to write a Java Application that will make this chatting easier
The plan is to make a simple chatbox, in which everyone can participate, much like the msgplus IRC-channel, but then in class
I'm even considering having all mobiles send out each recieved message to increase the range:
Like Frank, Ben and Tom are in the classroom, Ben can reach Frank and Tom via bluetooth, but Frank and Tom are too far apart to reach eachother. If Frank sends out a message, and Ben receives it, Ben will send along the message so that Tom gets it too. If a lot of people use it in your school, this could enable you to chat with people in a classroom at the other side of the school (although it will be pretty slow )

So how am I progressing?
At the moment, I have a simple chat program that I tested only on the emulator.
It's far from finished, messages sent quickly after eachother get lost, but at least It's a start

If you would like to test it, you can
I've attached both the jad and jar files to this post
For information on how to upload jar and jad files to your phone, use google It differs too much per phone
