There is a synchronisation feature in the recent releases of taskwarrior. It allows the same user with multiple devices to sync the data across all of them.
I already had tw running and synced on my ubuntu netbook and Android mobile. With tw now able to run on my pw3, it too joined in!
You need to set up your own "task server", which all the devices can access. However, Jack Desert has set up a free server, which anybody can use... unless, of course, your data is too confidential..!
