Peter,
I haven't seen any false colour due to optics - only from seeing effects. I'm no scope expert but I am pretty familiar with chromatic aberrations, purple fringing, etc in SLR lenses - I see none of those problems with this scope.
Here are a few samples in case anyone wants to judge for themselves - a couple of 100% crops are also attached here to save downloading the full files. All are unprocessed, straight-out-of-camera except for a RAW conversion in Lightroom:
1. Moon shot with the FLT-132, P-FLAT68 and Canon 5DmkII (ISO 1600, 1/1000 sec). Assuming the height of the moon is 30 arc minutes, the image scale is approximately 1.4 arc seconds per pixel.

2. Moon shot with the FLT-132, WO DuraBright 2" diagonal, TeleVue 5x PowerMate, and Canon 5DmkII (ISO 3200, 1/250 sec). Note that the 1.25" PowerMate vignettes on my full-frame SLR. Using the same scale as before, this image is approximately 0.26 arc seconds per pixel (theoretical resolution of scope is 0.89 arc seconds).

3. Double-transit of Jupiter (Io and Europa) and Great Red Spot shot with the FLT-132, 2" diagonal, TeleVue 5x PowerMate, Canon 5DmkII (ISO 800, 1/30 sec) and EOS Camera Movie Record at 5x zoom (recording the 100% crop of the centre of the sensor in LiveView mode). Same 0.26 arc seconds per pixel as above.

(I only have a YouTube link because the raw AVI is > 300 MB and still uploading. I'll update this link once it has finished uploaded.)
By the way, the Mallincam seems like a really great concept. I'd definitely go for one if I had a permanent observatory.
