Only compass that works as a data source for wind vector calculations, to my knowledge, is the Zander's. Of course, it is part of the Zander system (can't add the Zander compass interface to instruments by other manufacturers).

I would discourage anyone from adding an electronic compass module to their existing computers, as it's just not working properly. Probably due to extreme sensibility to pitch changes, and software unable to correct that.
If on a low budget, buy a working, used Zander set.
If on a higher budget, try the newer inertial varios.

I agree that accurate and real-time wind calculation is of very high interest to soaring techniques. I used it for years and I just can't adapt to fly woithout it.

all IMVHO, of course!

Even Zander compass was very sensitive to installation. I installed one Zander system to a LS8 for WGC years ago and calibrated it with factory calibration compass. It worked fantastically giving very accurate readings. After that my club bought similar system to D2 and it didn't work at all, even after many calibration attempts. I have flown third glider with similar setup, and that also did not work. We never understood why. With current knowledge of compass sensor installation problems, there might have been speaker or something too close to compass.
