I don't, other than to say that experimentation is easy - I bought my ultrasonic off of eBay. (bigger is better), makes the device more useful.
I use small spice jars for making my batches, and woody things last longer than squishy ones. i.e. orange rind dried is lasts longer than orange rind fresh. However, fresh orange rind gives a different taste and is cool if you're doing a cocktail night, or something. You can do things that you can't do any other way like this.
Cloves, Sassafras root, ginger, juniper berries, rosemary, lavender, sage. All have great effect.
Also, Ultrasonic makes EXCELLENT sangria. This is the only way to do sangria, IMO.
You can either use bitters to add to sangria, or just put wine and other things directly into the ultrasonic and infuse that way. It works great with herbs. For fruits, you should really just use the juice or crush them with a mortar and pestle. Any fruit soaking in the sangria is purely for show. IMO, all sangria should have sage in it. Sassafras in small quantities makes cheap red wine taste about 2 shelves better. YMMV.
This concept is quite well-known in high-end cooking. Nitrogen cavitation is another method of rapidly infusing (though not necessarily aging!) liquids with aromatics.
Ultrasonic boths -- as the OP mentioned -- is also another way of extracting more flavour from liquids. Both concepts are talked about in "Modernist Cuisine" by Myhrvold & co.
Yes - I got the idea from Russell over at the Ice Cream Bar in SF in Cole Valley. They use Nitrogen cavitation for all their extracts using the whipped cream bottles from Isi. I thought "cavitation?" and went to an ultrasonic because I already had one.
