"reliably" in itself is already a red herring.  Protecting you against
*what*, and under which assumptions?

For "I want my facebook and youtube and e-mail to work, even if one of 
my ISPs goes belly-up!", homenet + dual-prefix works.  It will not give
you perfectness just yet, aka "source address selection will not 
pick the best source IP for whatever definition of 'best'", but MIF is
working on optimizing this.  Your sessions will die if you are actively 
using the ISP that just died on you, but mp-tcp is one *demonstrably
working* way to handle that, get much faster session failover that BGP 
would give you (seconds, not minutes).

For "I need to run a datacenter full of stuff that need to have stable
addresses, no matter what happens elsewhere", I give you that BGP+PI
(or whatever other source of "your addresses") is a much better and
more reliable approach.  But for a barber shop that just wants their
internet radio to be there all the time, it's completely wrong.

Short form.  Longer discussion of the options and missing bits upstream
in this very thread.
