ETA for a bonded lines router

Bounded lines router is you have 2-6 WAN ports on the injection point and you have a standard switch at the exit.

It is made to provide decent connection when people are living in crappy places in term of internet coverage!

Not everyone is living in big cities, with tons of stuff.

My grand ma is living in a S***t hole and has a crappy satelite dish witch provides her a really crappy connection. No cell phone coverage, and landline when the ISP is whilling to repair!!

Or this can be implemented for high demanding people willing to increase their bandwidth!!
