This will be the last release from me for the time being. I had to dump Nano so I could squeeze in exFAT support, so you'll have to make do with Vi for text editing.
I've also made the configuration available on github, along with a simple script for building from source for the paranoid.

This release supports, by default, the mounting of USB storage with FAT16, FAT32, exFAT and EXT4 partitions.
Upon insertion of a USB storage device, the root of each partition will be probed for a new payload.bin, and if found will replace the current payload with the discovered file.
This release has, by default, ethernet activated and set to be configured by DHCP, as well as Wi-Fi enabled by default with the SSID "3GWIFI_XXXX" and the WPA2 passkey "12345678".
These details can be changed at any time by editing /etc/config/network and /etc/config/wireless respectively.
Thank you.
I hope you find it useful.
