There is only one I've seen that does at present - Bloxx, and while it's a
nice product it lacks a firewall.

Why is it simpler?  How would you go about filtering DNS?

If you're talking about the use of appliances for Internet access in
schools, it is pretty much the only way to do it.

Well they do HTTP proxy, as advertised.  So I'm not having a problem with
the appliances.  Sigh.

I have no problem with the Kontiki people not thinking about
school/corporate environments, it wasn't in their remit.  The BBC however,
maybe should have thought a bit harder about this when choosing a platform -
given their audience, and the amount of taxpayers money they spent
developing it.  But it seems that expecting developers in this Web 2.0 age
to have any semblance of a clue is too much.
