This does require cutting up the glove, which I am loath to do.

The fingers range from 100k to 500k ohm in flexing.  The PC
joystick port has four a-d integrators which measure 0 ohms
right away and are recommended to range from 0 to 100kohm.
The hardware works by polling, so the smaller the range,
and the lower the low-end value, the faster it works.

So, if you put 1megohm across the finger, you can drop the
input range to a small, quickly readable value using the
formula for parallel resistance which I have forgotten.
You'll read from 10-100 with this stratagem.

Being clever, you could integrate the Power Glove value
sampling code and the polling of the joystick ports.

You then need to do a calibration system to make the glove useable.
