[wp-xmlrpc] XMLRPC for Wordpress Mu

[Luke Mackenzie]

Hi,

I have been tasked with creating an API for retrieving and adding content to Wordpress from a flash application and legacy CMS (non-PHP). My plan is to utilise the existing default xmlrpc endpoint and add any additional functionality by creating a plugin which hooks into xmlrpc_methods.

A previous attempt had been made by another developer based on the following code:

This code looks unwieldy and poorly documented to me and my preference would be to use this approach:

I would be grateful if anyone with experience in this area could confirm that:

- I will be able to distinguish between separate blogs in an MU installation when both retrieving and posting data via XMLRPC
- I will be able to retrieve and post to custom fields
- writing a plugin is the way to go. 

We do not have the option of using Wordpress 3 as it is still in Beta and we are under time pressure.

I would greatly appreciate appreciate any input / advice.

Many thanks,

Luke.
