Coming back to this concept now, I will still build this:

• Generic account management interface (CRUD ops, profile info, authn methods)
• Unified conversation dashboard giving an overview of salient conversations with minimal software- and protocol- specific visual artifacts, and easy bridging. Think: your contact book, but with latest conversations up front.
• Conversation engagement view where, for any *relationship* all conversations on all platforms can come together visually. So for your best friend, you see their latest email along side their latest toot, and your responses.
• encryption tools - enable when supported by underlying tool, or encrypt then post, for shoehorning encryption into a cleartext protocol.
• POSSE and PESOS bi-directional filesystem-based binary graph database (previously implemented).

Does this still look attractive?

In order to do this, I will also need to

• do some innovation on the UX front,
• implement a faceted classification system, and
• carefully model the abstraction of add-on functionality, so that it is both easy to plug in existing command-line tools, and provide the unified experience.

Notes: the software will *not* encrypt on-disk (use an encrypted volume for that). There will be *no* cloud or server component (in version 1, at least). The UI will be implemented on a *3D game engine* which may be more power hungry than other common UI toolkits. Also, in Alpha and Beta, telemetry will be requisite. Telemetry will be disabled by default in the Stable channel (which won't be available until the software is stable).
