Yes this has always been a good solution for those systems which have 
runsocks/LD_PRELOAD available.  It's a little less userfriendly for people 
who aren't accustomed to the command prompt too.  (yes, KDE is starting to 
get some of those users!)

Thanks for the micro-HOWTO.  We should put this together with the KSOCKS 
documentation as an alternative method.
