Grapple is designed to be a simple network layer,
allowing the addition of multiuser features to an
application for as little as a dozen lines of
code. However, it also allows for more. It
features simple client-server networking that
keeps all clients aware of all other clients,
passworded servers, and data transfer via TCP,
UDP, or reliable UDP. Advanced features include
network messaging via push, pull, or a
combination, multiple methods of querying users,
user groups for client bandwidth saving, network
load reacting data transmission and
retransmission, background pinging to monitor
network states, server failover, and a fully
functional lobby system.
