Very good idea, something fun to do when inside on summer time!

( It is summer here right now, where I live, in Finland)
My question is, is this going to played via Hamachi or similar, or just using DW's own connect to host service?
Because everytime I have had Hamachi or similar installed to my comp, It somehow screws up my DW. It seems I cant use DW's own connect to host service after that, and it is annoying.
I have tried to make the correct changes to DW's danerouswaters.ini, but with no joy.
So if you guys decide after all to use Hamachi or such, please write down some instructions how to make it work, Thanks!
