hehe "Paranoid" mode would be fine.
first of all. it realy realy looks awesome.
i know you won?t release a private server.
but there are two arguments to do so.
1. security and privacy (paranoid mode will help) but the only way i?m sure is when i run this on my own servers
2. performance - buddycenter is usefull, but extremely slow. so when you do your job good, many people will use your monitor
and maybe it will be very slow
i understand that most of the people are not able to setup your custom tcp socket server, apache and mysql and so on
but there are a few poeple out there which can do
i think we can trust you about security and privacy (my stomach feeling hehe) (don?t forget to encrypt

)
and as long as it will be fast enough maybe there is no need for private server hosting
btw. can?t wait to see a test version
