PS these last show up as a soundcard in your Daw/max/supercollider/whatever - Im assuming you could daisy chain them using asio4all or something similar - but again they are not super reliable and the speakers are paired - but might work for a small installation. There are other bluetooth speakers around that might be more reliable and seperable. There are also wireless audio cables and other bluetooth speakers that are supposed to be more "pro" but I wouldnt know if they are fit for what you want to do :
these things will send a signal via bluetooth - can you daisy chain them ? I dont know : http://www.miccus.com/products/blubridge-mini-jack Then creative do a lot of wirless things including some multichannel soundcards again - I dont know if they can be daisy chained and they are recreational not pro audio devices . Their proffesional audio division made something called the "E-mu pipeline" which was a kind of wireless audio cable but then you're looking at 4 DA/AD conversions before the signal comes out the speaker: http://www.creative.com/emu/products/product.aspx?pid=18609 again I dont know how well they work but if they do what they say they do the time difference between channels "should" be no worse than a physical cable.
