How to make any pair of gloves work with a touchscreen

Here's an interesting idea (read: I haven't tried it yet) - boosting your touch screen device's responsiveness to input from your glove-covered fingers by making the material in your glove more conductive. I've noticed that when my fingers are cold, the address input screen of my GPS seems less responsive.

There's a comment on gizmodo that this idea will only work on thin gloves but I speculate that if you only sew the outer layer of the glove material with the conductive thread it should still work and you won't compromise an internal liner that is providing weather-proofing.
