[Gluster-users] Again on GlusterFS and active/active WAN Replication

I have a few questions about GlusterFS used in active/active WAN-based
Let first start with a little ASCII chart:
HQ Linux w/SMB share -> low speed link -> Remote Linux w/SMB share ->
In short I had to replicate a local server share on a remote Linux box,
and I would like to use GlusterFS (pre-seeding the remote side to lessen
first-sync bandwidth requirements). However, I realize that writes to my
local fileserver will be slowed down by the fact that GlusterFS use
synchronous replication between the two bricks.
At first I thought to work-around this issue using tuning the
write-behind behavior, but that seem to have no effect on replicated setup.
So my questions are:
1) it is not possible to increase local write speed while concurrently
issuing a background sync against my remote target?
2) in current 3.4.x branch, it is possible to use geo-replication for
active/active setup (I bet no, but...)
3) any advise of how to tune GlusterFS to suite this specific scenario?
Thank you and regards.
