Mitra v2.25.0 includes a functioning FEP-ef61 gateway, which portable actors can use to communicate with the rest of Fediverse.
I'm currently using a command line FEP-ae97 client, but it is very primitive, so before migrating to a nomadic identity I need to develop a better client.
One nice property of FEP-ae97 is that clients and servers are not very different. In theory one can even take any existing server like Mastodon and convert it into a client, because client-to-server and server-to-server APIs use the same data format. Servers send activities to inboxes located on other servers, but clients need to send activities to outboxes located on gateways.
This is exactly what I'm considering doing with #MItra. A special build that will work as an offline-first desktop client. Alternatively, FEP-ae97 can be implemented in mitra-web frontend, this option is less interesting, but will not require installation.
