I've got a problem where I have a Family Master FreeNAS at site A that replicates to Personal FreeNAS B (soon to be at Site B). Currently Sync is a A -> B ZFS Replications (Send/Recv).
However, as soon as B is at site B it will become my Main FreeNAS, which presents a problem- Senc/Recv does not allow sending changes back. So, I am going to need a method to send those changes back over a fairly slow link (7mbit - OpenVPN overhead).
I've got several requirements:
Does anybody see any pitfalls here I should plan for, or risks I can't mitigate and just have to accept?

I've got several requirements:
- "modified at A and modified at B" won't come up often, but I would like this to be left up to me to decide.
- Cannot just create a full copy of the data and then rsync changes around (Although a clone from the latest snapshot sent over and managed with a cron job would be acceptable, and the likely beginning of a solution)
- Would prefer it to handle interruptions smoothly as this isn't the fastest or stablest connection.
- Can't consume a ton of memory (local box only has 16gig), I have about 10TB of data.
