Hi,
while being new to kamikaze build, I have created a little package which I need for myself.
I'm just happy to be able to integrate things into builtroot-ng that easily *thanks devs*
After creating this package, you'll find it inside the Network page,
htc - the httptunnel client
hts - the httptunnel server
As it is just the first try for me to integrate something into buildroot-ng, it doesn't create any config files or bootscripts!
you'll find the executables in /usr/sbin (hts for server and htc for client)
If you find it useful and ask me nice, maybe I'll find the time to add config files and startup scripts 
I don't need them, cause I'll don't use predefined things and create my own
OK here it is:
httptunnel v3.3 (Server & Client)
1. just create a directory in trunk/package (eg. trunk/package/httptunnel)
2. create the file "Makefile" (without quotes) and put the following in there:
include $(TOPDIR)/rules.mk
PKG_NAME:=httptunnel
PKG_VERSION:=3.3
PKG_RELEASE:=1
PKG_BUILD_DIR:=$(BUILD_DIR)/$(PKG_NAME)-$(PKG_VERSION)
PKG_SOURCE:=$(PKG_NAME)-$(PKG_VERSION).tar.gz
PKG_SOURCE_URL:=http://www.nocrew.org/software/httptunnel
PKG_MD5SUM:=493cc0f5f21e9955db27ee9cd9a976d5
PKG_CAT:=zcat
include $(INCLUDE_DIR)/package.mk
