Streaming payment system for MakerDAO. Payment sources are defined as Taps and streamed into the Keg for pass-through distribution to the end target(s). Tokens are never at rest inside any of these contracts.
The Keg has pre-defined Flights which map human-level strings to distribution targets allocated by percentage.
seat() creates a new flight distribution.
revoke() deletes a distribution.
The Tap is the most common type of payment source. It is fixed rate that pump() can be called on it anytime to send any outstanding funds along. The funds are pulled from the surplus buffer (vow) via vat.suck(). Be aware that rate is unbounded and could potentially result in system flop auctions.
The FlapTap is a singleton Tap which forwards a fixed percentage that would otherwise be headed for flap auctions (MKR burner). This can be used to allocate a % of profit to be redirected towards other contracts.
