Visual linking doesn't seem to be that easy. Either two people have both one Sharingan from the same pair (Obito/Kakashi) or a Rinnegan wielder turns another person in one of his/her Six Paths of Pain through the chakra receivers, though I doubt it can be done if the victim is alive (see when Nagato pierced Naruto with the black rod, the Rinnegan didn't manifest in the latter's eyes, or when Madara tried to force Obito to revive him, no Rinnegan in the latter's right eye as well). I theorise also that if two Uchiha exchange eyes to achieve Eternal Mangekyō Sharingan, they can do visual linking just fine, but it's just my idea with no proof whatsoever. Another thing: when Obito is the Ten-Tails' jinchūriki, he can't phase through things.
