Yeap, there could be more information on the project homepage about this
(and any other issue:-)

Is that really that big a problem I wonder? You are inviting people to view
your stuff after all, so you can just ask them to stop again:-)

This does look a bit different if you host contents that is
visible for everybody... but then running owncloud is no different
then running any other web server on a server at your home. Just don't
get anything hosted there mentioned on slashdot:-)

> Secondly, I would consider it very important to allow for mobility.

Moving your data is hard with a web-server based approach. Basically you need
to move the data and then ask everybody to update their URLs.

A more "cloudy" approach would include things like encrypting data, applying
a global unique Id to each piece of data and uploading it into some form of
storage network. P2P comes into this, too, considering ownClouds "everybody
can run its own server" idea...

There are proposals on encrypted storage in the owncloud wiki, covering (parts 
of) this. Please comment on them!
