Quota Check on Gateway server in Split Functionality Cluster

Hello Listers,

I have determined that we are able to confirm the presence
of an mail box with the `check="true"` on our
gateway servers before
passing on to the central mail store, but how can I check on
a user's quota from a gateway machine.  We definitely do not
want to be
generating delayed bounces.  

I noticed the "g_gateway_data" option but the
language was a little unclear if that would help out.

Thanks in advance
