-    Fix serialize problem with JsonRestStores (2 ways... now?). Needs to return un-serialised data on GET
-    Decide on standard name of events: storeRecordRemove, storeRecordUpdate, storeRecordInsert sounds good
-    Chance client so that it uses new generic messages format
-    Finalise the tabIdHash function use -- is it really OK this way? I think so.
-    Finally, see comet actually work again in Hotplate
