+## HOWTO: Ident Table Snapshots
+
+How to take a consistent (single transaction) snapshot of 
+
+This will take somewhere around 15-25 GB of disk space on the database server
+(under /tmp). It would probably be better to stream this transaction over a
+network connection (saving database disk I/O), but I can't figure out how to do
+that with plain SQL (multiple table dumps in a single session), so would need
+to be a custom client.
+
+    ./ident_table_snapshot.sh
+
+## HOWTO: Dump abstracts, release identifiers, file hashes, etc
+
+These are run as regular old commands, and can run across the network in a
+couple different ways. We might not want database ports open to the network
+(even cluster/VPN); on the other hand we could proabably do SSH port
+forwarding anyways.
