Just wondering if there are any APIs to read/write Contacts/Calendar/Installed Apps/... yet.
I thought about writing an OwnCloud Sync app for the showdown that should be able to synchronize all that across devices, but now I'm not sure if this is even possible on Ubuntu Touch yet. At least I couldn't find any documentation on these cases.
Otherwise it might just be a file-sync (Hello, Ubuntu One?) app that can display the OwnCloud calendar/contacts, but can not integrate into the system as good.
