One current limitation of KJSEmbed is that we cannot connect signal/slot 
connections from a UI file.  So you have to manually do a connect() in the 
javascript.

As for startup time KJSEmbed is chained by Qt/KDE libs for startup, so you may 
get nailed there.  I am trying very hard in KJSEmbed for Qt4 to streamline 
this.
