Create Input Method component

Question

I need to make an Input Method for a language. It would function similar to that of the Kotoeri or Chinese components: namely after the inline input of some text, the desired Unicode glyph would be called. All of the references in the ADC pages presume I already have an input method, or can work with their example to make something like the Asian input methods. I do not want to start from scratch, but would ideally like to modify an existing component (swapping out existing data and dictionary entries with my own).
Curiously, I see that there was a session at the WWDC 07 that addresses the exact issue I'm inquiring about. Is this Input Method Kit something that will be available?

Below are critical observations that you need to be aware of:
2. VERY IMPORTANT!!!!!! Personally, saving a file as .cin locked up my whole system, and I had to login as root in order to remove the file. I'll never do that again. Thus my note is "# INSTALLATION: save as a .inputplugin file and put ~/Library/Input Methods/
# Once this is in the Input Methods file, you then enable the input method by going to the International keyboard
# input module and selecting your input method just like a regular input method is selected.
3. # If plain text, the file encoding must be Unicode (UTF-16) with or without an initial BOM (Byte Order Mark).
I made the edits using TextWrangler (http://www.barebones.com/products/TextWrangler/). This allows you to encode in UTF-16 (at the bottom of the file).
Also, there needs to be a mention of honor here to Tom Gewecke for his invaluable advice and support in correctly interpreting Apple's help sheet. Apple's sheet is almost correct, but the alerts above will keep you from creating a file that will crash your system like I did—twice.
