+- Overall framework docs
+
+- Finish Aussie Rules 4-State, for which I have complete docs now (yay
+  USPS and aupost.com.au for putting specs online. Too bad UKPost doesn't.)
+
+- Investigate USPS PLANET stuff
+
+- Higher-level objects that handle barcoded address blocks with correct
+  spacings and such (US, AU, UK/etc?)
+
+- Even higher-level objects that represent mailpieces and place the
+  above-style address block objects, FIM codes, "place stamp here" blocks,
+  etc, correctly?
+
+- Framework for laying out labels on various styles of n-up label
+  sheets, like Avery labels, etc?
+
+- Decide if Plessey is worth doing. MSI-like (MSI is actually derived from
+  it), but specs were never formalized. Probably only useful for legacy
+  applications. If you need it, mail me.
+
+- Get someone to test Code 11, or find a scanner that handles it
