AmFast <http://code.google.com/p/amfast/> is a new AMF0/AMF3 encoder/decoder for Python. - AmFast's core encoder and decoder are written in C, so it's around 18x faster than PyAmf <http://pyamf.org/>. - The encoder and decoder accept user-defined Python objects that allow customization of the encoding/decoding process. - Supports custom class mapping. - Supports remoting with NetConnection and RemoteObject. - Remoting headers can be exposed to callable targets to allow for quick implementation of authentication and other AMF features that rely on headers. - Supports data persistence with SQLAlchemy <http://www.sqlalchemy.org/>, including remotely-loadable lazy-loaded attributes. - Supports Actionscript code generation for mapped classes.
