The biggest drawbacks here are that we either need to set up a server that's going to host sensitive user data, or we need to help everyone that wants to use this set up Dynamic DNS, punch holes in their firewalls, configure their routers, etc. so they can host the data themselves.

(The former approach has some legal issues that arise that are a bit of a concern, while the latter would be quite complicated for the support ninjas.)

Not ruling anything specifically in, or out - just giving you a snapshot of our current thinking on this subject.
