I think you would be better off taking a look at the rnid site click here as you are more likely to find someone who has the same/similar prob as you, and has found the solution. There is a forum on the site click here
I'm not saying that nobody will be able to help from pca, just that they will be better able at the rnid.
To keep your missus happy until this is sorted, I 'spose you could get a webcam and sign ;-))
Hope this is some help.
