Is there anything that could be done to make it unnecessary to pull the 
complete metadata for every update?  For example, IIRC this is all sqlite 
data, but what if this was in a plain-text data dump form where something 
like rsync could be used to efficiently transfer only those bits that have 
changed.  Client CPU time to reconstruct the DB is probably cheaper than 
the bandwidth.  Maybe such a mode would only be used if the DB size 
exceeded some threshold.
