Research on new non XMLish RPCs

I was searching for a better RPC (other than SOAP, CORBA, RMI, DCE etc) and found some new kids on the block

1. Cisco: Etch - Limited language binding
2. Google: Protocol_Buffers - Just message wire format. Doesn't talk about RPC. Do see this post
3. Facebook: Thrift- Very new and more like IDL CORBA, DCE family

And then I came across REST paradigm. I then researched its advantages with respect to RPC and found steve vinoski's blog post titled "The Technology Adoption Side of RPC and REST" which puts REST in the dissruptive technology bucket and RPC in the sustaining technology bucket. Very interesting read indeed
