I'm writing a mobile OPML blogging interface - so that I can post to my OPML blog from my phone or PDA. I've got part of the way there - I've managed to post a file to my hosting.opml.org account from PHP. I'm using Keith Devens XML-RPC Library to do so - because though I like Simon's library, Keith's is simpler and closer to my style of coding (hacky, nasty, brutish and generally not OO unless necessary). What's nice about Keith's library is that I'm using his XML library (which is about the quickest way to get data from REST XML), and his XML-RPC library returns in exactly the same format. 
I've got nothing against doing it in an OO manner - but decent XML libraries should be part of all languages without having to use objects. 
Hopefully I'll have something to show in the next day or so. 
There's quite a lot of work in getting this to work - but it's a lot of fun.
