+== Other Ideas ==
+
+Some more ideas that would be worth pursuing...
+
+=== Mail Client Integration ===
+
+Although the original focus of imip-agent was to produce mail handling
+programs that would be [[../MailIntegration|integrated with mail systems]],
+some effort has been directed towards making libraries and components that
+can be reused in other kinds of programs. Indeed, the
+[[../CalendarManager|management interface]] employs the libraries in a
+different way from that of the [[../AgentPrograms|agent programs]] and acts
+as a kind of calendar client that just happens to use the same
+[[../FilesystemUsage|filesystem structures]] to store information and
+control the software's behaviour.
+
+It would therefore be interesting to use the `imiptools` package, possibly
+with some modifications, in projects like [[https://mailpile.is/|Mailpile]]
+and other Python-based mail clients. And a process-based method of
+integration, similar to that employed by the [[../Testing|test suite]],
+could benefit even non-Python programs, with imip-agent-based programs
+being run to perform certain tasks and to update schedule records that
+would then be interpreted independently by the calling programs.
+
+Where end-to-end encryption is being used for mail communications, such
+client integration would be essential for imip-agent to be useful: the
+[[../AgentPrograms|agent programs]] are unable to inspect messages without
+access to the recipient's secret keys, and unless a recipient is willing
+to run their own MTA on their own computer and grant access to various
+keys so that the MTA or imip-agent can perform decryption, the only way
+that imip-agent might see the actual content would be as part of the
+recipient's mail client.
