I gotta agree here. If the workplace overlords start prepping for her arrival with reminder emails, "awareness bulletins" that might get posted in the kitchenette / break room area, etc., -- these tend to make the existing employees feel like they are catering to this new employee in a way that, no matter how good she is, no matter how hot (sorry) or not she is, there will be resentment towards her. I think the better approach is to introduce her to the team, remind folks that it is a workplace, and that HR still accepts complaints, and acts on them.

To take all of the marketing bias/hype out of the equation, the exercise you must do is to write out your Non-functional requirements first.
Example:
- A solution that successfully integrates documents, spreadsheets, email, calendaring, contacts, tasks, and does so seemlessly.
- A solution that can support a single-sign-on approach to password/identity management
- A solution that facilitates usage across devices (physical desktop, virtual desktop, roaming laptop, handheld device)
......

You get the idea.

Then, evaluate the solutions based on your requirements. Is it Google Apps? O365? 3rd party hosted Exchange as a service?

There are a lot of choices. Consider what it costs to run a server, maintain licenses, etc. compared to these *as-a-Service options. For 10 people, buying server infrastructure is overkill.

already slashdotted. who knew.

it this way: In your attic, place a switch, with runs to each of your upper floor rooms, and a run to the basement. In your basement, place another switch, with runs to each of your lower floor rooms, and connect that attic switch in. Now your whole house is chatting at up to 1000baseT if you splurge on the gig switches. I've seen the attic/basement connection ran out a window and down the outside of a house. I've also seen that line get hit by lightning and take out a bunch of gear, so think twice about that, or at least put some grounding straps on it (check with an electrician who can advise you on this) to keep the lightning at bay. Typically, your older houses have hollow, easily accessible internal walls. Good for fishing wires up and thru.

Hire some good Linux admins. Preferably someone fired for violating a policy in the past, because he/she will know all the rules, where the fulcrum of those rules are, and how to lock them down and prevent their abuse.

Prepare to be hated though. No one likes going to school, er, I mean work, to sit in detention all day long.

Will track down where any MAC address is connected. If they have the IP, they can get the MAC. If they have the MAC, they can get what port it's plugged into. Find the switch, find the cable, and air-gap it. I know this, and I'm not even a network guy.
