Eskimo,
If somebody wants to do that, I guess they could leave it logged in. I'm not sure it would be worth the effort though. I'm more concerned about the extra load it could put on the Host. Maybe HTC could automatically punt folks after a certain period of inactivity.
As for folks switching countries to get resets, Pyro has mentioned perk multipliers for being outnumbered may work. That way, you would get more perkies for fighting for the country with the least number of folks, so it would tend to counter-balance the effect.

A pig is a pal, who'll boost your morale, Though mountains may topple and tilt.
When they've blackballed, bamboozled, and burned you, When they've turned on you, Tory and Whig,
Though you may be thrown over by Tabby and Rover, You'll never go wrong with a pig, a pig,
You'll never go wrong with a pig!" -- Thomas Pynchon, "Gravity's Rainbow"
