Heh... I'm glad to be the squeaky wheel, but thus far I've taken an 
implementer's stance with LB and haven't learned the code.
I will try to take a look but it may be the weekend before I have any 
appreciable time for it.

I can provide you hardware, if it will help.  The thin clients I'm using 
can be had for US$10 on eBay.  If you're in the states, I'll ship you one.
