R/retroshare - A retroshare relay/server to always have everyone's message

There’s a Reddit thread about a RetroShare relay server to always have everyone’s messages. Here’s an excerpt:

What if in a retroshare network, there are “dead hours” where if you send a mail or post on a forum, nobody will receive the message, therefore it won’t be transmitted until you connect again at a more active time.

Isn’t this what UPSYCLE Store & Forward proxy is supposed to solve? I’m wondering what is the current status of the Message queue, @arie.

Hopefully we can discuss this at OFFDEM.
