+* Nodes which act as both observers and direct participants in the ledger are not supported at this time. In
+  particular, coin selection may return states which you do not have the private keys to be able to sign for. Future
+  versions of Corda may address this issue, but for now, if you wish to both participate in the ledger and also observe
+  transactions that you can't sign for you will need to run two nodes and have two separate identities
+
+* Nodes only record each transaction once. If a node has already recorded a transaction in non-observer mode, it cannot
+  later re-record the same transaction as an observer. This issue is tracked here:
