public void run() {Other things. To emulate this on my notebook, I had to unblock the emulator and some zaysit or something program so they can access Internet. Apparently, Wireless Messaging API needs initialization. Also, I updated my hosts file to show the current IP address, just to be safe.

In this context, prototyping means writing the absolute minimum amount of throwaway code that's needed to answer a specific design question.
Sometimes you can't really know whether a design will work until you better understand some implementation detail. You might not know if a particular database organization will work until you know whether it will meet your performance goals. You might not know whether a particular subsystem design will work until you select the specific GUI libraries you'll be working with. These are examples of the essential "wickedness" of software design—you can't fully define the design problem until you've at least partially solved it.
A general technique for addressing these questions at low cost is experimental prototyping. The word "prototyping" means lots of different things to different people (McConnell 1996). In this context, prototyping means writing the absolute minimum amount of throwaway code that's needed to answer a specific design question.
J2ME is definitely a limited api. We will need to code a lot of the UI by hand, developing new widgets as we go. Designing a good UI will require quite some work. I have been giving considerable thought to our UI and the more I think, the more I am convinced that we should adopt a very no-frills approach for the UI. One that doesn't try to get in the way of the user.
On a cursory look, I do feel that making any sort of connection should be fairly simple given the high level of abstraction in the Connector api.
So much for now, I'm heading to work.
