A rarely discussed out-of-the-box talent of the Tab (and many more mobile devices with the correct software) is DLNA.

For those that don't know, DLNA is a standard by which to very easily stream media between devices on a home network (eg. WiFi). Many people that have consoles like Playstation 3, have experience with DLNA as they can look through their server's media via an on-screen interface, and play it directly on the big screen, without manually pushing around files or moving physical storage.

But DLNA goes far deeper than that.

The PS3 is what's called a DMP or Digital Media Player. The job of the DMP is just as it sounds: it plays content from a DMS -- Digital Media Server.

But there are two other DLNA mechanisms worth mentioning. These are the DMR and the DMC. The DMR is a Digital Media Renderer, and the DMC is a Digital Media Controller.. With me so far?

The DMR can play media, but it has another talent: it can be controlled by a DMC! This means that the DMC is a remote control that can control the content that comes out of the DMR!

But the DMC can do more than just control the DMR. It is a coordinator of sorts and can have content residing on a remote DMS (server) played on a remote DMR! I would imagine that in the case of a handset, a DMC can also push it's own content to a DMR.

This takes the pain out of sharing media on a home network, and puts it in an idiot-proof package. Though it may seem confusing, wielding it would be as simple as selecting the thing you want to play your media, and selecting the media that you want to play on it, from a user-friendly application on your Android handset. Any DLNA compliant stereo, TV, computer, digital photo-frame, or home theater, can be controlled right from your DLNA device! As it turns out, there are MANY DLNA compatible devices and lots of software for custom setups.

Samsung includes AllShare as part of its application suite for the Galaxy S and the Galaxy Tab, in fact it's a major selling feature. I'm not sure if AllShare is a DMS or a DMC, but I would guess it would be the latter. Needless to say, that DLNA is an extremely powerful feature and a welcome bonus to an already stunning device.

I'm excited by this functionality. To think that me and my GF can effortlessly select movies from my TAB and watch them directly on the big screen is an exciting prospect. Even more exciting is putting on some music over my home stereo, using only the device, and with a slick interface!

DLNA also allows for easily sharing files (upload/download) and has facilities for printing documents. However I'm not sure if these features are supported on the Tab.

If anyone has more info on AllShare I would be interested to know more. Other than that, I'll do more research and come up with more information!
