I am certainly open to Ford Motor Company sponsoring my flight to
wherever this summit is taking place and we can dispose of the problem
of my failure to attend.

My talk would be titled, "How Bill Gates dreamed of using RPC to court
his future yet unseen wife"

Hell, that might even be qualify for a TED talk as well.

I promise I will buy you a beer when I land.

My usage of the term "HELL" probably indicates that I am a crude
American without the fine polish of our European counterparts, like our
allies at Digia, with whom I have true respect.

To put it into automotive terms, I likely drive a F-150 and not a Prius.

But I will continue with this monologue until they cut me off.

There is the local case and the remote case across the myriad number of
devices.  There are just a lot of extra variations in IPC across
Desktop, Android, and IOS.

For example on Local: http://www.slideshare.net/jserv/android-ipc-mechanism

For Remote, I think you are left with UDP broadcast/multicast for
discovery/reconnection purposes.

The reason why RPC died and HTTP/REST dominates is the simple fact that
HTTP/REST is SIMPLE.  Not 10 million bloody incomprehensible parameters
like RPC.

Whey does SOAP continue to decline?  Extra complexity for little or no
gain.  Who wants to worry about WSDL?

With HTTP/REST, If you do not have network connectivity, the ergonomics
are dictated by a simple timeout and an HTTP/404 error or something like

WIth RPC, you could NEVER tell why it was not working.  But you were
SURE it was NOT working.  Sometimes, you were not sure it WAS working.

Let alone a human being operator getting meaningful feedback
and the library supporting such simple feedback.


So be very careful in getting distracted by all the IPC unification work
just to make replication function across device platforms.  There may be
an easy alternative for both local and remote cases.

I know, I use UDP broadcast for both Android and IOS because it just
works. And the code is SIMPLE.

While I understand the sentiment, it would be helpful to understand what you think Replicant can do to keep falling into the same trap.  Or are you of the opinion that an easy/sound RPC mechanism isn't possible?
