SkinLF 0.3.1/ArgoUML/LimeWire

SkinLF 0.3.1 is a nifty skinning library for Java applications (and applets).
Also, ran across my first two Java apps today that use Java WebStart for simple one-click install and run. Jext and ArgoUML both have started making use of it. I’d be surprised if it was too far in the future before Freenet started using it as well.
Speaking of Freenet, check out LimeWire, a peer-to-peer file sharing application based upon the Gnutella protocols that is written entirely in Java! It looks sexy, is easy to install (although it doesn’t yet use WebStart) and is just the sort of thing to draw people towards using Java for their everyday applications.
