Oh my! I was so silly not to take a closer look at the Samsung AllShare client featured on the Galaxy S/Tab! If you look closely at the video and pause at 00:24s mark, you can clearly see that the AllShare client has 3 options:

1) Play or download media from my phone on a player
2) Play or download media from a server on my phone
3) Play media from a server on a player, controlled by my phone

The third option is the interesting one. It implies that if you have a DLNA compliant server (DMS) setup and a DLNA compliant player (DMR), then you can use the Tab as a remote control to play the server contents on the big screen or home stereo!

Here's a link to the video again, in case you want to see for yourself.

So here's a scenario: You have a home server tucked away in a closet that you've ripped your DVDs and CDs to. It has a whopping 2TB of movies and music. You feel like watching a movie with your lovely partner. You pick up your tab, open the AllShare application, select the third option, select the movie, then select your TV. Seamlessly, the movie starts playing on the TV! You get full control over the movie right from the Tab (play, stop, pause, seek, next, prev) in case you need to take a leak. Even better, you can set up a playlist to string together media!

Here's another scenario: You're going to be going on a trip. In bed, while reading an e-book, you think it would be nice to listen to that new album you got, and perhaps a favourite movie or two for the flight. You open the AllShare application, select option 2, find the album and two movies, select download. The download starts in the background and you get back to your book. In the morning, you're ready to go!
(Disclaimer: do dock the device before falling a sleep, as a night of transfers would seriously run down the battery)

Yet another scenario: You're at a friends house and want to bore them with pictures of your latest trip. Reluctantly they agree and then immediately regret the decision. You select the AllShare app, select the first option, select the unintersting pictures, select your friends TV. You are happy, your friends are bored! Another DLNA win!

I could go on, but you get the idea. It's not hard to see the benefit of connected devices, even just for media sharing. As a bonus, the DLNA spec is WIDELY adopted and the official site lists more than 8700 devices, and this certification does not include software! Add a Linux/OSX/Win PC in the mix, and there are tons of connectivity possibilities.

Truly a great out-of-box feature for this device, with a very nice interface.

For other devices, DLNA is well supported as well! Other android handsets/tablets can use AndRemote to make the devices act as DMCs. iOS apps can use an app called PlugPlayer for DLNA support. Even Maemo has LinuxMCE for DLNA support! Needless to say, desktop OSs have multiple projects supporting this spec as well.
