The app itself is good, but I think GreenTunnel is a bit too heavy (140 MB) as a DNS spoofing app. Also, it requires NetFramework 4.5 too that not everyone has. Another good alternative would be DNSCrypt which is lightweight (less than 10 MB) and already portable.
EDIT: I just tested the app and it doesn't leave any other trace on the system beside %AppData%\greentunnel
and %AppData%\green-tunnel
. No registry too. I think you can portablize it yourself. Something like:
[DirectoriesMove] AppData\greentunnel=%AppData%\greentunnel AppData\green-tunnel=%AppData%\green-tunnel
Use 7-zip (or similar app) to extract installer files without installing it. The green-tunnel-X.X.X-full.nupkg
file, to be exact.
