Default Measuring Beer in Kegs

I just thought of this idea and I wanted know if anyone had already done something similar or can think of a great way to make this happen.

Yesterday I went to my keg to draw a pint for my girlfriend and before I walked away I decided to gauge how much was left in the keg. I did this by seeing how light the keg was and estimating how much was left. I went back to my girlfriend and said "the keg is almost tapped, enjoy the beer before its out". "How can you tell its almost out?", she says, and thats when it hit me.

Can anyone think of an accurate way to measure the beer volume in our kegs?

COLLABORATE!

just put the keg on a scale empty and keep it on one while drinking and you will know when you are aproaching the empty keg weight

I open up my keggerator door for a bit and see where the condensation forms on the keg. It gives me a general idea of where the beer level is at.

Similar to the above. Pull the keg out for 2-3 minutes and read from the top of the condensation line.

Some issues with the scale idea:

I don't have a scale large enough to take that amount of weight.
A scale would take up floor space unless it was the exact size of the bottom of a keg and many keezers are already very tight fits. Aside from the floor space it would also make the kegs taller.

A leave in place solution that would not require too much if any modification of existing keezers would be preferred.

Condensation is pretty accurate but not exactly DIY, instant read, or easy to read (for non-brewers)

There was a thread going awhile back about this. I don't think much materialized about it but I'd love to see someone way over engenier a solution to this problem.

This is a neat start if you have not seen this yet, Sparkfun's the tweeting kegorator.

I'm not going to search for it so you'll have to google for yourself. But I remember reading an article about this guy who use an arduino to twitter to status of his keg volume. I think he used a commercial kegerator, and a normal 15gal sanke keg. If I remember correctly, he had weight sensors which he used to weight the entire kegerator.

actually I will google it for you

Count the pints you pour. 40 pints per 5 gallon keg.
