Hi
I saw that system, or one like it, on petco today. It could probably be rigged to work the way you want it, I haven't done it.
Are you having a problem with low humidity in your tank? A better solution could be a household ultra-sonic humidifier. I'v seen picture posts in this forum of them in use. You can get one for about the same $$ at Wal-Mart. It will hold more water and you could plumb it into all the tanks. I'm not exactly sure how to do it, but it has been done. Add a digital timer to turn it on and off and your ready to go.
Also, what I'm looking at is a misting system sold by http://bigappleherp.com
It's $99.00 and has a 2 gallon tank, comes with a timer and can be hooked into multiple tanks.
Hope this helps.
Leif
