While they have plans for a DIY colorimeter too, the software does support the Spyder3 - I've had it running and you get a virtual information overload out of it. Will probably take a bit to figure out how to use it properly because the documentation is in French.
I bought it to use with my Pio 710HD RPTV but that died before I got to it. I'm now going to use it with my Panny PT-AE4000U projector - yes, it says the Spyder3 does front projection... it even comes with a holder to mount it on a tripod. I haven't quite got to that yet - the system's only one month old.
