Well this is news to me and if so, count me in please. If you have a mailing list please add me to it, I want to check into this further; i.e. open source, purchase of a library, terms, etc.

The small overhead of AMF you mention is well worth it from what you describe.
Please provide a URL for installing such a setup, and _PLEASE_, even if we're all experienced programmers, stick to simplicity in terms of making the setup instructions verbose and very clear; we programmers often do not step back and realize that any and all instructions should be explicit and not skip over steps, presuming someone should know something (this not only works against people just learning, but against people who are tired, have localization language issues, etc.]

you should not have any problem with packet filtering.
- You can turn on GZIP compression with remoting just as you cand with
SOAP. That means it be even smaller. Remoting cuts out all the extra
metadata so its always going to be smaller.
- GZIP compression doesn't improve the client side processing of the data,
it actually hurts it in a small way. This is why AMF is so much faster than
SOAP. Flash uses DOM to parse XML, due to this you will see that the client
side parsing time grows exponentially with the size of your data. AMF grows
linearly. Even with small datasets AMF is much faster due to the simplicity
of its serialization.
Its not difficult to setup a simple benchmark test. Do this and you will
quickly see how much better AMF performs compared to SOAP, especially with
large datasets.

A few comments.
> * Binary transport
So is SOAP when you turn on GZIP compression in your container. And I would
argue that binary transmission can be a bad thing too. What if a firewall
used on a corporate environment has packet filtering turned on. Does that
firewall have an AMF filter and did the firewall admin know what it was? I
spent oodles of time working in CORBA. IIOP is a binary protocol and I cant
tell you how often we bumped intot his issue in a true distributed
application. We actually used to tunnel the IIOP through HTTP a lot to
avoid this.

Not true with GZIP turned on.

So does XML web services in Flex.
