Yeah, I finally finished it. It's available at
http://unitethecows.com in the downloads section under clean p2p apps. Phex is already a great client thanks to Gregor and others, I just added skinLF functionality.
Gregor, I will send you the changes I made shortly so you can see what you think of them, and maybe solve switching from skinLF back to metal/motif etc.
The thing that took me so long was the jComboBox. SkinLF uses a renderer to display them in themes (like aqua). Phex also uses a renderer on the search combo box to convert raw search data to something meaningful, and it preempted skinLFs renderer, so no skinning at all appeared on it. I finally combined the two renderers. Should have done it earlier
