Well, you can look at distributed OSs like amoeba or distributed
middleware like ISIS.  A good place for transaction info is
the Transaction Processing Performance Council (www.tpc.org)

For my part, since everyone is so patent crazy now, I just roll
my own... (and document the hell out of the dates and processes.)
