(Because it is unfortunately not possible, before anyone asks.  I do not 
recommend any further UIs be implemented for the external UI extension, 
which is being phased out, but for now as Rui says hosts (inherently) 
have to implement it themselves)

Note a new Suil release will be out very soon, the last round of 
releases was broken in the UI department (stupid oops, go me!), you 
should use Lilv and Suil from SVN (or just wait a day or two) if you are 
implementing this.
