ok, ill try to explain this.
i live in a student house, our landlord pays for a 1mb line to the house.
i personally own a 3.6mb vodafone dongle (but this is satelite and is therefore not always reliable).
my idea was for some programs to access the internet via the 1mb connection (i.e. downloads) and for other programs to access the vodafone dongle.
the only reason i would like to do it like this is that i dont want to have to use the vodafone dongle for everything as it is paid for by my dad and i dont want it to get too expensive, but at the same time i want to be able to have access to the 3.6mb line.
i do not want to merge these connections, i would like to keep them seperate.
