 > A test suite and interface you can use to implement a connection. A connection is understood as something that offers mechanism for writing and reading data, back pressure, half and full duplex streams. This module and test suite were heavily inspired by abstract-blob-store and interface-stream-muxer.

 The API is presented with both Node.js and Go primitives, however, there is not actual limitations for it to be extended for any other language, pushing forward the cross compatibility and interop through diferent stacks.
 
-> **IMPORTANT** - Tests are still not finished nor the interface

+notes:
+  - should follow the remaining Duplex stream operations
   - should have backpressure into account
   - should enable half duplex streams (close from one side, but still open for the other)
   - should support full duplex
   - tests should be performed by passing two streams
