Yes.  I have my own portable ip space (geeze was I thinking right in '92)

So essentially that makes MY internal stuff get priority going out.

I run a website that sends out a fairbit of traffic (5GB per month) so I DO 
notice people d/l from the website.  [car geeks on that website]

Yes.  Indeed - 150.101.234.58 - most external services hang off that (mainly 
because of the way Internode do routing of extra ip space to get around 
Tel$tra wierdness).  So this drops the priority of my websites' outgoing 
packets.

Yep.  Valid, and yes on 512/128.  Downlink's pretty much irrelevant as we 
don't shape it - but hey.

Yep.
