Pont Mirabeau - an UPnP bridge

written by Frank, on Jun 30, 2009 10:56:00 PM.

What started over a year ago as a vague idea and got more concrete in a first prototype last October, is now ready for a first public beta - Mirabeau, an application level proxy for UPnP devices using XMPP as a transport to establish a connection between two or more local networks over the Internet.

Or in less technical terms, it allows the DLNA capable TV at your parents place to access for instance the images of your last vacation stored on an UPnP MediaServer in your home.

Mirabeau is part of Coherence and utilizes the D-Bus interface there to create a transport layer over XMPP with the help of Telepathy’s tubes.

Philippe and I will give a presentation about it during this years Gran Canaria Desktop Summit.

Mirabeau addresses the issue that UPnP is only meant to be used in a local network. With Mirabeau we are able to easily interconnect two or more networks and the UPnP devices therein. All that with a simple, well-used setup - Jabber, and without the need for complicated VPN-tunnels or similar techniques.

Philippe wrote already about our first successful - world premiere - connection with our two networks in Spain and here in Germany, where we tested the whole infrastructure with the UPnP-Inspector.

What I would like to highlight here is the point that arbitrary UPnP devices do participate in this.
Mirabeau is a transparent bridge for UPnP devices on the application level, not only an ‘I can share my media collection between two instances of the same software’ setup.
Which is of course nice too, but we lifted that to a more higher level and instantly integrate everything that can talk UPnP - PS3, Xbox 360, Totem
