Immutable sharable zero-copy data and streaming

A computer program product comprising one or more computer storage media having stored thereon computer-executable instructions that, when executed by one or more processors of a computing system, cause the computing system to perform a method for sharing data between multiple computing entities, the method comprising:

• an act of populating a buffer with data;
• an act of classifying the buffer as an immutable buffer, wherein the classification protects the data populated within the immutable buffer from changing during the lifetime of the immutable buffer, and also protects the immutable buffer from having its physical address changed during the lifetime of the immutable buffer;
• an act of granting a first view of the immutable buffer to a first computing entity;
• and
• an act of granting a second view of the immutable buffer to a second computing entity, wherein the second view is different than the first view.

A system comprising:

• a memory having a buffer;
• a populating computing entity that acquires data or generates data, and populates the data into the buffer, after which the buffer is classified as immutable, wherein the classification protects the data populated within the immutable buffer from changing during the lifetime of the immutable buffer, and also protects the immutable buffer from having its physical address changed during the lifetime of the immutable buffer;
• a plurality of consuming computing entities that consume data from the immutable buffer;
• and
• a view providing entity that provides different views on the immutable buffer to at least some of the plurality of consuming computing entities.
