I've found them inside tyres before but never used them, the theory is sound.

A cupful of water in the tyre will do the same thing.
I've been using steel gunshot (cheap) in the beemers and my landcruisers tyres for years, seems to work. This was how they balanced all tyres before lead weights and affordable balance machines were thought of. As soon as I get Levo to convert the valves to tubeless argy will go the same way.
I use the same weight per tyre as the dynabeads website.
Old ball bearing balls are just as good.

Bit of a non-starter there... 
The theory is sound but it doesn't take into account rapid speed/direction changes.At work[on cars] we occasionally get tire shake complaints on supposedly recently balanced tires.A spin on the balancer shows the weights in the wrong spot,after repositioning and another spin it gives different weights/positions. We had the Hunter rep demonstrating the newest,latest,magic machine we had just purchased and used a wheel off a car one of the other techs was working on and he tried 8 times to get a repeatable result with no luck using all of the mounting options available. Breaking the bead to reposition the tire on the rim resulted in a gusher and about a pint of water from the tire. The same happens with Fix a Flat and all the other snot that is supposed to work miricles. I would think bearing balls might shot peen the inside of the rims as they seek their place of equlibrium.
They fling out to the outside of the tyre even at very low speeds. When you go from walking pace to stop they may fall down to the bottom but I wouldn't call that shot peening. Water would work but I would have thought not a good idea especially with steel rims and it would interfere with fixing them ie certainly not fix a flat and maybe stop you using the tyre plugging things, but maybe not.

I wouldn't recomment putting water in a tubeless wheel (Laverdas are supposed to have inner tubes). Actually, I wouldn't recommend it for a tube either. I just suggested it as a cheap and cheerful alternative to fancy ceramic beads if anyone wanted to give it a try. The best solution is to balance the wheels properly with fixed weights.
If it's such a good idea, why aren't moving weights standard fitment on all vehicles and other rotating machinery? I'll tell you why ...
Freely moving weights can never balance a wheel as well as fixed weights, as illustrated by the story from wdietz186 a couple of posts back. The reason is that the wheel needs to be rotating off-centre (out of balance) for the weights to be spun out to the furthest point from the centre of rotation. Once they get there, their weight will bring the centre of mass of the wheel back onto the centre of rotation, restoring the balance. But then there will be no out of balance force to keep them there, so they'll be free to wander off again, allowing the imbalance to come back. The net result could be a constant slight off-balance or an oscillation between balanced and imbalanced. Or a combination of both happening at different speeds.
