WTKs - Creating a network of them / using several KVMs at once

Question

Hello,
I've been using the J2ME wireless tookit for almost two months, and I've already have a look at the documentation, tips and a more-than-beginner approach in programming area, since I use EclipseME. But I need to create a small network and I just need some ways to set off one small project :/.
I do know that every MIDLET is nothing without a KVM. The toolkits provide a way to let small simulated devices to load them as tiny apps. They are real powerful machines, that can let us view every aspect of the application before actually loading them in a mobile. The problem is when we need to use more than one WTK :(
Let say someone created a GUI program using Eclipse that shows a canvas of loaded 'squares', that is, instances of the class 'MobileSquare2D'. He or she wants to link every square to KVM virtual machines running in the background and loading the simpliest application (e.g: one that pings to one's requests). He or she can think about using WTK since its emulate mobile phones well. But how about the communication between the KVM machines? And how about the cluttering of wireless toolkit consoles opened up?
So my question is:
- Is there a way to run several midlets, in several wireless toolkits in one machine? If so, is there a way not to use its GUI? (that is, not graphical output, since I only want to send a data from one WTK to another?) If its not possible to run many WTKs, someone know an alternative to WTK? Maybe a 'MIDP Midlet loader'?
- Is around there any opensource project of a WTK? Thats because I would need to use a Java SE1.4 class that outputs in my GUI these small retangles, as said above, each one being a mobile phone, that is, everyone running KVM on them.
As I know I would have extremme work if reinventing the whell (in regard to implementing a UDI program), and Im only a student, it could be more productive if using classes that references KVM and loads small JAR files (or even the simplest program which uses only a .class file) Which can access KVM and external protocol modules and create a small simple connection of virtual mobile phones, in order to do experiments like receiving a ping response and sending XML files to be outputted in the other's screen.
I will be very glad and stimulated if someone helps me a bit here. I do know the great potentials of using KVM and its midlets not only for mobile phones but network sensors, as well. I tried to get some help with other Wireless Toolkit developers but they appear to not exist at all :/ And googling about it wasn't useful (no topic about).

1. sym.$("video").hide(); will hide all the video elements, then you can selectively show a particular video  as sym.$("Vidoe01").show();
2. Write a function in the compositionReady like:
          sym.hideShowVideo = function(name) {
               sym.$("video").hide();
               sym.$(name).show();
And call this function for each button like sym.hideShowVideo("Video01");
