Agreed, once it is put together it would be more like a finished product, but as long as you make the Arduino-compatible MPU re-programmable (break out a USB mini connector w/ an ftdi IC) you would be ok. To make it slightly modular you could add a break-out port (somehow) that allows for either a bluetooth module, x-bee module, or wifi module as you already have a unified breakout board for all 3 of them. Would let users get hand data to pretty much any wireless enabled device of their choosing and no hardware modifications would need to be made.
Lateral Finger Motion: I'm not a sign language expert, but a quick google search of the sign language alphabet shows that it might however I don't think that would be a hard problem to fix. You can't bend the flex sensors sideways but you can add conductive fabric on the sides of the fingers that could act as switches to indicate whether two fingers are touching and de-bounce them in software.
Different sizes: You can go with the un-spoken average glove size, which is simply the size of gloves that random companies hand out at running races in goodie bags. Boulder Running Company and Runners Roost seem to always be giving out gloves and they seem to fit most people. If you avoid putting sensors on the finger tips you can also make finger-less gloves. The flex sensor doesn't need to run along the entire length of the finger to get proper readings.
You could re-create the sign language glove & make it more robust/easy to wear/water-resistant (cover everything in a thin coating of some conformal coating material or this: http://www.youtube.com/watch?v=AqQ3IyyObsk)?
A link to your previous sign-language posting:
you could embed the resistive strips into the glove fingers, use conductive thread to extend the sensors to a microcontroller that is connected via bluetooth to a cell-phone or some other wireless speaker. You could also mount the gyroscope's/other sensors using the flexible PCB material. Some sort of coating would help secure the IC's to the flexible PCB material and the material itself would help make a glove that could be easy/comfortable to wear and not have an Arduino hanging off the top of your hand. Make it open source & allow the community to hack away at it/improve upon the design, could become a cool product.
I haven't had a chance to play with all of your "wearable" circuitry items, but I could see the glove becoming a more robust version of this actual product (I knew I saw a more formal/non-academic version of your previously-mentioned post before...):

If people need help using this sensor LabJack has a nice AppNote that can help you understand how to use this sensor.
No public wish lists :(
