I am not going to reintroduce the routing filter, as such, for PC92. I 
will be discussing this later on in the summer when I have a bit more 
time. The routing filters were there to solve (or at least reduce 
significantly) the problem of loops of old-style routing information. 
The big problem with them was that they also stopped all directional (eg 
talk) messages as well. PC9x is designed to get around that. It is 
better, but still not perfect.

For RF links, I would recommend doing a set/isolate on that node. This 
will stop all PC9x traffic and quite a lot of other stuff as well.

The central question is this: do we really need a realtime view of all 
the users www are logged in on the system? If the answer is yes, then 
something like PC92 has to exist, if no, then most of it could be 
switched off.
