Oxygen, webservices and Opensource

I have some questions for the list.

Does anyone know anything about the folks at WSO (wso.org and .com)? Are these guys really opensource people or what?

Are there any shops around town doing reasonable rates training in IT skills, especially related to OSS?

Anyone doing any webservices in Linux using WSDL 2, DIME (obsolete), MTOM? And why does debian include php-net-dime but there isn't and equivalent php-net-mtom?

For those people like me who hate all the @#$!!@ abbreviations used today.

WSDL = Web Services Definition Language MTOM = SOAP Message Transmission Optimization Mechanism DIME = an abondoned MS supported standard which MTOM has superceded.
