Susano-o is shared by Mangekyou users who can control both powers (Sasuke says this).
Tsukuyomi also appears to be shared by Mangekyou users considering Madara himself, said he'd cast Tsukuyomi on the moon.
SO, now, it's all down to the ninjutsu eye, which seems to vary... Sasuke and Itachi both have Amaterasu. Could be because they are brothers. I remember this was said by Danzou...
If we were to assume that logic^, Kakashi's Kamui is a power from his ninjutsu eye, he lacks Tsukuyomi because he only has one Mangekyou eye, thus, can't activated Susano-o as well. If we were to assume Tobi's right eye utilizes the ninjutsu power, then we may also make the assumption that his brother also had that power... So basically, brothers (at least) share the same ninjutsu power of the Mangekyou. Tsukuyomi and Susano-o are shared by all Mangekyou users though the nature of those similar techs may vary based on skill, chakra level, alignment, etc...
All speculation, so don't take this as fact.
