I just read OpenCola's technology overview.

Interesting they're wanting to do better than Akamai at caching content
closer to the user. I believe this could work, if they attain critical mass.
Also interesting is that they're not using XML-RPC or SOAP.

My comment: I think XML-RPC or SOAP could do what they do. I don't know
their business model, or if their goal is to get lots of compatible nodes.
If would seem so, XML-RPC would, by far, be the best choice. SOAP would be
second, and a new flavor of XML-over-the-wire, imho, a distant third.

I know some OpenCola people are here on this list, so I thought it would be
interesting to learn why they're gambling on a new wire format, instead of
joining up with the existing formats. It's a lot of work to get developers
to swing together. It would also be interesting to support them in our
software, but that's more work for us if they use something different.
