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.
