[olug] Home bandwidth monitoring

[Rob Townley]

I liked ntop, but AFAICT (years and years ago), it was a desktop app
instead of an always running service.

Untangle for at home use is free, but there is some form of magical
incantation to the download process needed.  However, not totally sure if
the free home version has url categorization.
