Xp Com

XpCom ( "Cross Platform ComponentObjectModel" ) is a set of InterfaceDefinitionLanguage spec for CeePlusPlus and JavaScript (via XpConnect), used by TheMozillaProject (of cross platform MozillaFirefox fame) for creating extensions that serve in RichInternetApplications.

The OpenSource XpCom technology supports threading, but are not required to be re-entrant. This is where outward similarities with MicrosoftCorporation's ComComponent end. XpCom does not have the elaborate performance related implementations to make thread safe distinctions between in-process and out-of-process situations. The XpIDL compiler has its roots from the Corba world.

MozillaXul extension is MozillaBrowser-based tool to develop RichInternetApplications. see http://www-128.ibm.com/developerworks/webservices/library/co-xpcom4/

Some SoapProtocol based XpCom components exist already. What practical opportunities, if any, exist for people wanting to expose legacy BigIron information to intranet? [I avoid internet because WebServicesSecurity is "BleedingEdge" technology]
