I was thinking about building a tool with opposite functionality - Getting chat messages delivered on email.

Reason - To switch to a full-linux based phone, as clients for those platforms aren't available. I rarely use chat message so, intuitiveness is not the concern. But when I do get a message, I would like it to be delivered via an encrypted email service.

Little thought went into this - Parsing messages from web app of the respective chat apps on a SBC.
