Yes, this is part of my default configuration for embedded systems.

Both.

I've considered application specific versions of this scheme.

Stupidly so IMHO.  I often see systems with a mission of moving
massive amounts of message traffic logging data orders of magnitude
larger than the size of the actual message.  Doing so naively results
in the servers spending much more time logging than doing the work
they're intended to do.  Logging is important and at this rate it
costs real money to accomplish so it deserves to be engineered
sensibly.  My rational is that where a gen_fsm is spawned for each
transaction it should simply do it's work and before terminating send
it's State variable term, usually a record, directly to a log handler
(e.g. disk_log).  To have the worker for traffic doing string
processing for an human to possibly read a long time later makes no
sense.  Log binary data to disk and format just the data requested, at
request time, formatted for the requestor.
