Perhaps this is a multipart question, but I deal with a lot of calendars in my life, and want to know if there is some way to sync them all together, and maintain appropriate privacy.

So I have a family calendar that my ex and I maintain for kid events, and I have a personal calendar for my own life, and I have an Outlook work calendar, for work. Ideally I'd look at my calendar on my Android phone.

Is it possible to sync them all together? Is it possible for there to be one calendar to rule them all on my phone, but have the other calendars blank out spaces that are from other calendars, but only show the blanked out without the details. (I don't want my date with Miss Hottie to appear that way on the family calendar, and I probably don't want my visit to the proctologist to appear in the corporate exchange server.)

Are there tools available to do this?

Bonus question, can I do the same with my to do lists?

Double bouns question -- how can I solve world hunger and help us to all live together in peace? :-)
