This is the base address to use for finding updates from Eclipse; you can set an update site for http://www.alephnaught.com/Eclipse/ to grab the latest and greatest. Note that I'm using Eclipse 3.0 right now, so the V. 2.0.0 plugins only work with V. 3.0.
I just wrote an email file(s) plugin - it adds a Send menu item to the File menu (much like you see on other platforms) with a pull-aside menu that has Email File(s).
I've written a small plugin to display the system properties of the default run-time JVM (that's the VM where code gets executed, not the one running the eclipse instance). You can select cells and copy the value.
