Hi, let me put everything I was requested to comment on in one post:

About Push support:

Last thing I know is that the cancelled push support might be available through the store after PR1.2 is out; the push support included images only.

Distributing what's currently played via DLNA:
That's not possible using the usual Rygel + PulseAudio route for at least four reasons:

a) PulseAudio is missing at least one module (module-rygel-media-server)
b) Even if it had those, the version of Pulse used is missing the two patches that fixed that module
c) Rygel is missing the DBus consumer module (because it causes a sh*tload of wakeups)
d) Rygel is missing an upstream patch needed to make the DBus consumer plugin work with templated URIs (which the PA support uses)

That said, if you get the GstLaunch plugin compiled and installed, you could try to follow the instructions here: http://askubuntu.com/questions/83611...er/99892#99892. The Rygel version used in PR1.2 is this commit: https://meego.gitorious.org/maemo-mu...175d6ae8575b9f

Regarding 1080p streaming:

Again, that does not work out of the box (for non-technical reasons I hopefully can announce next week) for any random format but only for H.264 high profile videos with EAC3 audio.

This is easy to solve though with developer mode, just edit /home/user/.config/rygel.conf and set strict-sharing to false. If the file does not exist, you can copy it from /etc.
