For three months I think I would even take a dye-based ink out and put 
Epson carts in. Then I would get a friend to at least turn it on once 
every two weeks or one week maybe. Epson inks slide through the head 
like butter, far less clogs- but they still do occur and if it was me 
I still wouldn't let it sit idle for over a week or two.

I don't know about that. Since the cart is always full, it may work 
even better than regular carts, which decrease pressure head with ink 
level, but I really don't think anyone knows for sure. The big problem 
would be evaporation through the tubing or air getting in the bottom 
of the CIS cart, or so I would imagine. I've had both good and bad 
luck with vacuum filled carts and CIS/CFS. It seemed to depend more on 
the climate than any thing else. And moreso on how long I left printer 
idle between prints, even a quickie draft print keeps the nozzles more 
behaved than not printing, for me anyway.

I don't have knowledge enough of the new Piezotones so someone else 
will have to answer that.
