Keeping more to the less expansive here ...

May I ask that the context within which things sit be included, and how to
get there?

- suppose the asterisk (or whatever) system here is to be a vm, for
simplicity's sake. Extrapolating that to a standalone box should be
relatively self-explanatory, in this context (of kwlug).
- how to accomplish the vm? (1) 'live cd' (2) building it 'from scratch'
(let alone CentOS vs *buntu based).
  - perhaps not demo (2) so much as describe the issues, differences,
functionality, complexity. Dealing with (1) only (loading trixbox?), makes
it real - presumably the purpose of the topic.
- networking / internal connectivity issues (pinging / making internal
calls from elsewhere in the local network, via this vm)
- maintenance issues? e.g. Security updates, to what extent required /
prudent, backups, etc.
- box replacing router / direct connected to ISP, vs. not - requirements
and steps, safety, reliability for rest of current functionality (e.g. web

Guess this would have to be a separate night. Not sure whether it's better
