So effectively running a copy of the primaries ACLs on the secondary.

Yep, I know it's not not ideal, but I'd rather have it that way for
now until I get something 'better' sorted out (hopefully soon!).  I
have been looking at VPSs and have found slicehost.com appears to

with 100Mbit quota for 20 USD).
