No Nintendo has not made a deal with Microsoft for 360 downloads, but someone over at the Xbox Scene forums has found a way to run an emulator through MCE pc to your Xbox 360.
At this time there is no way to select the roms in a menu. Everything has to be done in a config file where you can change the rom and other information. Also keep in mind that rom files of original NES games may have legal ramifications if you do not own the original game cartridge.
From Xbox Scene Forum:
I've attached a link to a version of NESCafe that works through Media Center on the Xbox 360. This is currently setup to run at 480p (Widescreen). You can edit the nes.htm file if it does not fit correctly on your screen. I haven't found a way to add a menu for the roms list so you will have to edit the nes.htm and change to whatever Nes rom you want to play. I've included a Public Domain rom for testing but have verified Zelda1-2, Excitebike, and TecmoBowl and all worked. Please do not ask for ROMs as they are quite easy to find (Google - "Nes Roms").
INSTALL: You will need to extract the rar into C:Documents and SettingsAll UsersStart MenuProgramsAccessoriesMedia CenterMedia Center Programs on your media center box. It took a bit for the icon to show up under More Programs but it finally will.
NOTES: Sound is not functioning, Media Center 2005 is required. If it locks up you will need to run something that warns you that it is a web page and check the box that says "Don’t show this again". Once you do that it should run fine. I created an MCL that just went to Google and then checked that box. I've also attached an image with the mapping of the Xbox Controller to the corresponding keyboard keys.

Update: The current version does not allow for sound through the 360.
