Lot of interesting links on web services can be found on this page
Currently I'm working on the project which involves distributed web services and after carefully examining SOAP and REST we have decided to go REST way. One of motivations is that SOAP is extremly blotated standard which adds a lots of complexity which in most cases doesn't solve problems which cannot be solved REST way. Do not be fooled by simplicity of SOAP::Lite API - read specs to get idea how complex is it.
