- The Wii uses SD cards for external storage
- You can copy SOME files from the Wii to your SD card, provided the file in question isn't copy-locked
- Hell, they even tell you in the friggin manual who made the file system stack

You can't copy Virtual Console ROMs between the devices, but you can copy channel data and saves. I've copied the channel data for Sonic the Hedgehog (Virtual Console) to an SD card and uploaded it. Have fun picking at it, we might be able to create channels that run unsigned code:

Creator of embedded functions
Apparently Nintendo went cheap again, and used a pre-existing set of libraries for embedded systems. Because of that, they have to tell us what they used. So here's the list:
PrFILE 2 FAT file system
PrMAIL mail client
PrUSB/Host USB stack
All of these were created by eSOL. If their English webpage wasn't broken, you could request for information on these. Also, if an exploit for, say, the PrMAIL client was found that allows people to run unsigned code, you could use the Email/Wii Message Board communication features to load homebrew on the Wii.
That's all I got. Better than nothing :P
