U can do some place in clowd(already is). And Layouts will be shared by link.Hello DoubleTapInside and thank you for this very important question!
Unfortunately sharing virtual Android (and soon iOS) layouts is currently only possible with your own account between different devices. BUT we are already working on this so it will be possible to share your layouts with another user by entering his/hers user name (email associated with account). This will probably be done using the same menu where "export layout to server/cloud" is located an will be named "export layout to another user". After selecting this option another dialog will be shown with an edit box to enter username/email.
We will do our best to include this feature in the next big update that is almost ready.
