New issue 588 by [email protected]: Add delta mechanism to the encoding
http://code.google.com/p/protobuf/issues/detail?id=588

Its not a defect, its a proposal for a new feature.

i'm using protobuf as meta-data protocol in video streaming system.
my metadata is for each frame in the video stream.

mostly nothing in the meta-data changes between frames but i'm still sending any frame full message.

the feature i propose is some delta mechanism that will automatically check whats changed from last time i was encoded and encode only the "dirty" messages. in the decoder side i want him to understand the mechanism and "remember" the part of the message that has not send this time.
