[erlang-questions] failover pattern

[Garry Hodgson]

i'm looking at putting together a system that will include
a/b pairs of machines for each major role, to allow for 
failover between pairs.  starting to think about doing that
in erlang, i can see that all the parts i need are present, 
but i'm not sure if there are standard ways or best practices
to putting this together.

i expect that each pair of machines would have one of them
globally registered with the role they play, and that they'd each
link to the other so that they could assume that role as needed.
maybe something like the "negotiation techniques" in the (old)
erlang book.  but i get kind of mired down in the details.  i'm also
not sure how this would interact with the supervisors/applications
notions in OTP.

can anyone provide some insight, maybe pointers to papers,
tutorials, or code examples?

thanks
