depending upon how deblocking is implemented, it is possible to use deblocked samples for intra prediction.
Well, certainly if you implement it in the order Jean-Marc was describing, you could apply deblocking to pixels along interior edges before using them to predict adjacent blocks along an exterior edge, but I believe that was one of the "not implementation friendly" things Minhua Zhou was complaining about. It means your hardware can't pipeline reconstruction of those neighboring blocks until it has the deblocked pixels, which is fairly late in the process.
