Hmm, well the scenario I was thinking of was having database writes sped up, in the sense of reducing network latency between the user and the server. I guess the syncing aspect is going to be most complicated part. I was thinking that I could have some logic that stores where the user's nearest DB is as part of their user info, and just store their data there. But still not sure if that's the best way. Thanks for mentioning Citrus DB, I looks like they have an open source version that I'll try checking out.
