Barney,
I doubt, very much that we will see a webcam on the OneT+, but I would certainly be up for tinkering with a soldering iron if it were feasible. But then again I would be (very much) surprised if the little beast could cope with the resource demands of a webcam, let alone finding an application to run it.........but we can dream.
My wife and I use SKYPE a lot to keep in contact with friends and relatives abroad and it would be great to have that app on this little OneT+ so that the Grandchildren could have that opportunity.
