I had a feeling that a VERY cheap multimeter ran an 
AC current thru the cap, and measured like a resistance, but 
I could be very wrong... perhaps the designer of the worlds 
best 'budget' multimeter can tell us!
Perhaps we could have a MOTM multimeter (not THAT crazy an idea).

You would think that if you had say a 10k resistor in series with 
an unknown cap, and sequentially applied 10v AC at say 10Hz, 100 Hz, 
1K etc and looked at the voltages developed across it, you could 
work out esily and fairly acccurately not only the capacitance but
also the effective series resistance.
