Thought this was a good line of thought to discuss, as it may be useful for focusing ML design considerations as well.

One can use DSLR Controller App ($8 USD), and an OTG cable, on any supported Canon Camera (i.e. 600D with a $40USD wireless router  http://dslrcontroller.com/guide-wifi_mr3040.php), and view a 1080p image on their smart phone.  This is not revolutionary, but if you log in to a wireless network, then things get interesting because you can put a chromecast stick on an HDMI port, then send or screen cast a clean 1080p out signal to your HDMI monitor.

Perhaps you want to get a Hauppage HD PVR2 for less than $200 and record clean 1080p MP4 video to a laptop as well!.

Actually very cheap laptops could be used here, basically HDMI with 4G of memory.

What's beautiful here is that the HDMI outs on your Camera are avoided, so you still have the Liveview screen, and the output is not compressed 1200x800 like streaming from the Canon HDMI ports. 

Some might argue why not use EOS utility via usb cable and record video to your laptop.  The big benefit is the wireless placing of the camera for streaming or on a jib/slider.  This to me is much more set friendly, which is more common for streaming.   You may not need the HD PVR2 if you just want a monitor but what the hey, recording to disk on your laptop while viewing on Liveview LCD, Phone, and 27" HDMI  monitor is not bad at all.

This kind of eliminates the need to add clean 1080p outputs features to slower cameras via ML.  But if DSLR controller could run with ML raw video on your camera then this takes it all to a new level.  Anyways I think this is a useful discussion and would like to know if there are even better wireless uncompressed 1080p video solutions out there that would work on cameras with slower card writer speeds (i.e. 600D and above rebels, 70D, 6D, etc.).

Danne, nice video.  But it seems 15-20 fps was the max. limit on the TP to phone. 
I would like to screen cast video at 30 fps for instance.   
would be interesting to see if usb cable from the router can handle 30 fps?
As the android device could be used to send wifi HDMI to the wireless network
& then via chromecast to HDMI monitor.  Hopefuully 30 fps.

Another point to note, is that DSLR controller app is reported to work with ML as long as you dont shoot raw video.
So ML increased bit rate should provide better picture.

Unfortunately You are streaming Highly Compressed Video from the Chomecast or any other consumer Streaming HDMI device.
The Image quality will be not very good for focusing etc...
my 2 cents

I tried this set-up but no luck.
DSLR controller app did not run well on my Samsung Galaxy II.
Chromecast did not sync across the network with it.
I had Magic Lantern on my camera, and could get DSLR controller to run but ofcourse
keep away from RAW, as that will sink DSLR controller app.
I tried on both the 70D and 600D, cant recommend this system.
