A packet ID may have a specific "direction" of communication, in that an endpoint may either act as a _requester_ or a _responder_. A _requester_ is an endpoint that drives all of the communication on that specific packet ID, while the _responder_ is responsible for providing a timely response to the requests it receives. A _responder_ for a specific packet ID should never send that packet ID unsolicited; either the packet will be ignored or the other endpoint will close the connection. Any packet ID marked as bidirectional may be initiated by either endpoint at any time.
A _blind requester_ is an endpoint that sends out a packet of a certain ID and either does not expect a response or expects a response on a different packet ID.

## Sockstamps
Because epoch time is not standardized across systems, an intermediate layer of date/time transmission must be used between the client and server so as to handle time dependent interactions. Therefore, a "sockstamp" will be used in place of the context-dependent implementations of epoch time.
