Eclipse is a kind of universal tool platform - an open extensible IDE for anything and nothing in particular. The real value of Eclipse comes from tool plug-ins that "teach" Eclipse how to work with things - java files, web content, graphics, video, etc. Eclipse allows you to independently develop tools that integrate with other people's tools seamlessly.
SBLIM (pronounced "sublime"), the Standards Based Linux Instrumentation for Manageability is an IBM Open Source project, intended to enhance the manageability of GNU/Linux systems. It does so by enabling GNU/Linux for WBEM, Web Based Enterprise Management, a set of standards defined by the DMTF and fostered by the WBEMsource initiative.
