Hantek - build additional kernel modules from GPL source

[gicho]

First post here, but - I've got the GPL sources for kernel 3.2.25 of DSO5102P, made some small tweaks and everything builds fine. Then I re-configured the kernel and got some additional modules - usb lan, usb wireless, bt, etc.
Now I am looking for some assistance to use them on the scope. Ultimate goal is to get automatic "dropbox upload" of screen captures ("save") over LAN/WiFi/BT. Maybe I will need USB HUB to be able to connect a storage stick and the wifi/bt/lan? But maybe I could skip this - I suppose that one ("current") screen capture could just fit in /tmp and be uploaded from there?
Any ideas about a simple console style linux tool for "cloud" uploads? Or to network file system?
Any notes on rcS modifications and maybe wifi startup would be helpful too.
