To quote from his site (linked above), roughly translated:
"This program allows to simulate the dev_flash from USB. Allowing a Custom Firmware. We may modify the files of our new dev_flash (USB) as we please, without running the risk of throwing away the PS3.
It is a beta version, probably find bugs. I will continue working on it when time permits me. Remember that suffers no risk to the console. All that is changed the new dev_flash'll be doing really USB.
• Syscall PEEK and POKE.
1. Copy the "FTP server" the entire contents of the / dev_flash the USB (the root).

iLoader is an opensource BETA specifically designed to run with the Half Byte Loader which currently works on any PSP that has Firmware 5.50, 5.55, 5.70, 6.00, 6.10, and 6.20 including on the PSP Go and also via HEN and PSP Custom Firmware.
Koens Loader is currently closed source in Alpha state, and PSP iSO files must be decrypted via CFW PSP and loaded in the unpacked format (not from an .iSO image) in order to run.
While few PSP games including Crystal Defenders are reported thus far to begin loading and then crash, work continues on both projects with the authors seeking help from those with C/C++ programming for the PSP.

The POC video's caption simply reads: "The impossible just became possible!"
Finally, HERE is the USBGecko Log for those curious how it works. Check out the video below and long live the Nintendo GameCube!
