This looks cool. At first pass, I have one big question: are there any facilities or even just plumbing for syncing between installs / front-ends?
SaaS/cloud approaches have real downsides in terms of ownership but the big upside is access from multiple points/devices (home desktop, browser on office machine, personal laptop, mobile device, etc). Obviously SaaS isn't the only way to do that, centralizing around self-hosting or some syncing feature can work too. Anything like that on the radar?
