web-services and alike

may be this post seems a little strange. But since i discovered XML-RPC a little while ago (thanks to Stig's installer) i really want to implement some web services, just to get more into it. Since i think XML-RPC is really a cool thing and it can be used to really push something onto the web which didnt exist until now :-). For example, which is probably one of the simplest: a friend was asking me if i didnt have a web-service for retreiving stock rates. So i am just trying to collect some ideas here, may be some of them also fit in PEAR. The main problem is to have people/companies provide content this way, right? So may be we can implement some kind of system, PEAR-based of course, which makes it easy to "build" web-services. Well, just some thoughts :-) any ideas? looking forward to your guys' input -- Wolfram ... translating template system ... http://wolfram.kriesing.de/SimpleTemplate
