@Steven +1 Good idea, and include the URL of this thread. :)

Thanks for the answers everyone, I blogged about my final solution: lukecyca.com/2012/diy-soda-water.html

comment What debuzzing coil should I use to get rid of lamp hum?
Are you sure that a 10µH coil is going to work? I showed this circuit to my EE friend who concluded that the coil would be saturated and useless, so the dimmer would see a capitative load and potentially blow as a result. He calculated that it would need a 145mH coil instead (which is expensive!). I'm afraid I'm beyond my EE ability with this project, so I will probably go with a standard debuzzing coil, or just live with them hum. :) Thanks for all of your effort!

I like the sound of your setup. What is the procedure to carbonate the water? Does it automatically periodically draw water/CO2 into the corny keg to stay topped-up? Or do you make individual "batches"? Any other details or photos you can share would be wonderful!

I tried a GBPC3504WDI (same as your suggestion, but rated up to 400V) and the buzzing became even louder. The doubled frequency is perhaps closer to this bulb's resonant frequency. I will scrap the rectifier and might try the coil instead.

This means I'm giving DC voltage to the bulb, right? Do I need a smoothing capacitor, or will the full-wave rectified sine waveform be enough to stop the buzzing?
