Although I pretty much believe you're trolling, peaceful voyages would be comparable to a biologist from the midwest spending several weeks traveling to spend a year in Antarctica researching a microbe. Eventually, if a civilization develops enough, they will have the resources to satisfy their curiosity. However, it is just as likely they will be scavengers looking for pretty fur and make the resource extinct. In a long enough timeline contact is inevitable and one or the other will happen. Might as well make sure it happens gracefully.

If seti style contacts are established, any actual contact is likely to be through time-capsule type care-packages that take millenia to arrive. Maybe eventually carrying biological samples.

I imagine Stephen Hawking because of his celebrity status and his disability is developing some sort of persecution complex and is likely to view aliens in the same context. Yes, when we deal with enough people there will be a few bad eggs. And, the more people we deal with the more likely we are to encounter the really really bad eggs. But, we can't hide in our houses. The vast majority are good people and will help insulate from the bad. Hiding does nothing to insulate us, only leaves us exposed in a different way.

Survive pressures and temperatures? Where is your vision, you're not thinking like a maniacal spacelord! Did you or did you not take maniacal space-lordery at Uni? Who needs to survive the pressures when you can blow the whole planet up and pick up the interesting pieces. Don't worry, if you limit the explosion most of it reform in it's own gravity well. Or in the case of a gas/liquid giant, find the interesting stuff via RADAR/SONAR type systems and push it out the other side via LASERs :) Ooooo, giant nets! Giant space nets lowered from orbit! THAT'S IT! Or, how about a giant claw lowered from geosynchronous orbit like the Hughes Glomar Explorer. You'll get much of it to the surface....

Carbon shields have been used before, was bad idea with bad consequences. The Windscale research reactors were built with a significant amount of graphite for absorbing neutron radiation. The graphite was great at it. But, the energy would build up and spontaneously release itself as energy, and/or fires. Sure, they had work arounds. But, the workarounds gradually stopped being useful and the entire thing went up in flames eventually. Cleanup has just now really started, after over 50 years. Granted, there might be a safe way to use carbon once and change it out. But geez, carbon dioxied waste is one thing. Nuclear/spontaneously combusting carbon waste is another....

Don't forget, a good diamond is basically one big carbon molecule. A diamond's not only imageable, but you can feel/hold/interact with it.

What are you trying to accomplish? If you want neat and pretty, that needs one type of thing. If you are trying to organize the cables behind the computer, that needs another type of thing. If you are only trying to neaten the cables between computers, that needs another. You building a rack-room or want something professional? My only concern was getting in-between device cables off of the floor and above doors. Went to home depot, bought 1.5 inch PVC Pipe mounting clasps (used to hold pipes to walls), and suspended them 8 inches from the ceiling. Then ran the cables through the clasp. To manage power-cables behind desk, I strap-tied the power cables to the desk, leaving other ethernet/keyboard cables which will move around loose. If you want something to impress girls, don't think having neat cables counts. Most women that have seen the cables dangling from my walls are more than a little worried.... Keep meaning to string LED lights along them to make them look less disturbing.

Static configurations are available already, not the intelligent ones being requested. Has sufficed for what I needed:

To have print page break add: <p style="page-break-before: always">

Also, to hide odd font and underline for links:

<STYLE TYPE="text/css" MEDIA=print> <!-- A { text-decoration: none; color: black } --> </STYLE>

Yes, they have to be massaged a little.
