iPXE. Here is how to add this useful tool to your grub4dos multiboot pen.
1. Download the ipxe.iso from here and save it directly to your grub4dos USB boot drive (e.g. /ISO folder).
2. Add the menu option below to your menu.lst file:
You can also just add the ISO file to your Easy2Boot USB drive.
You can use iPXE to boot iSCSI, AoE, TFTP, VLAN and via other protocols too, but here is how to test the HTTP bit.
You might also like to try the netboot.xyz ISO. The netboot menu contains many linux (Live and Install) and other payloads which will automatically download and run from the netboot server (see website for full list).

To test it, you can use RMPrepUSB and test it using QEMU straight away (it seems to work with NAT!). Press F11 in RMPrepUSB to boot from the USB drive and then select the grub4dos ipxe menu you have just added.
When you see the 'Press Ctrl-B' prompt (first one or 2nd one), press CTRL-B quickly to stop it trying to boot from another source.
You have now successfully booted to linux over the internet!
Now try it by booting on a real system using exactly the same two commands. You will need an ethernet connection and a router.
iPXE does have some WiFi support too!. Unplug the Ethernet cable and try it on a netbook or notebook using the following commands after you hit Ctrl-B:
help will list available commands or there is a command reference here.
If you want to try booting a whole set of different OS's across the internet, try netboot.me at http://www.netboot.me/. Download the netbootme.iso file and add it to your grub4dos menu:
Fully automated, no typing required, just boots straight to the menu shown below, works in QEMU too (press F11 in RMPrepUSB to test your USB drive).
netboot.me has no WiFi wireless support (no iwstat or iwlist commands) so you need an Ethernet cable.
