For this you will need ethernet support in U-Boot. There are two (?) 
options to achieve this: Add support for USB ethernet dongle in U-Boot 
or use a Beagle expansion card with ethernet.

Regarding USB ethernet dongle, there are some basic USB patches for 
Beagle U-Boot on the list. But I'm not sure how much work it is to 
enable them to support USB ethernet.

For ethernet on expansion board, there is TinCanTool's Zippy board 
[1]. To access ethernet on this board from U-Boot, an U-Boot OMAP3 SPI 
driver is missing.

Both options are not ready, yet, and need some development work. Any 
help is greatly appreciated!

Cheers

Dirk

Btw.: I added U-Boot list, it is the better place to discuss this.

A third option might be to support RNDIS or CDC usb gadget support and
use the usb port with beagle.. tom might be able to comment better.

This is one of my development activities.
The cdc usb gadget is the gadget in the usb/cdc branch I am working
to first support.  I think I am fairly close to seeing some real traffic.

The goal is to get the usb/cdc branch into the mainline at the same time musb 
support has been added.
