Ooh... that's fantastic! Is this robust enough for lots and lots of data syncing? That is, if I import 1000 records while offline, then plug into the mesh, will all the devices in the mesh get all the changes? And if I had made changes on the other devices will that also get merged into the new device that just joined the mesh?
Thanks!
