Nothing more complicated than running

xcompmgr -fF -cC -r7 -o.65 -l-10 -t-8 -D3 &

in my .xinitrc and setting the transparency on individuals windows using 
transset-df.  Random crashes (SIGSEGVS with the occasional floating 
point error in the  nvidia signal handler function) would crash X every 
few days with no noticeable pattern, although others have complained on 
the nvnews.net forums of crashes when certain KDE apps (kopete) are 
running.   If the stability problems continue, perhaps the strategy of 
enabling Composite through GLX will work better. XGL was more stable in 
that it did not have random crashes, but leaked memory so bad that after 
3 days it would get killed anyway. :)
