On wind instruments they're usually called multiphonics rather than double stops.
well, that does make more sense.

On the flute there are two "normal" ways of playing 2 or more notes at once - singing and playing is the easier, and can be very effective - try playing a scale on the flute and singing in thirds, or a tonic pedal. This usually changes the timbre A LOT though and is usually just a "special effect".
well, i tried this, and somehow couldn't remember how to make a noise
not using the flute! rather confusing. an interesting technique, but i think i need a lot of work on my singing before i'd ever use it (i'm rather lacking in those advanced singing techniques like, you know, being in tune).

The other way is by playing certain fingerings, not being a very competent flautist I'm not sure about these, there is an excellent website that explains them -
http://www.phys.unsw.edu.au/music/flute/virtual/main.htmlthanks for the link - that site is pretty interesting! (now i actually know why the flute makes a sound...)
unfortunately, none of the multiphonic fingerings seemed to work for me :-( they just sound like a slightly airy normal note. i suppose i need to play around a bit with the embouchure and see what works.
