You sound like you're asking for a WiFi KVM (keyboard, video, and mouse).
Hardware KVMs are somewhat rarer now than they used to be, as software alternatives are now good.
You might look at something like this:
I have used good HDMI over IP products and good WiFi bridges, but never tried them together. On the software side, I was impressed with HP's RGS, but there are a ton of alternatives now. For small form factor PCs, I like the Brix Pro series.
Thanks for joining us.
What are the worst mistakes we are already making on connected devices, and what should we be doing to make them less desirable as targets?
CF cards are IDE, but with a smaller pin-out. If you have an adapter between the laptop IDE and the CF form factor you might be able to either plug the HD into a newer box with a CF adapter or plug a CF card directly into the laptop (assuming there's a second slot... or possibly even slaved on to a single cable if there isn't).
Personally I'd try PCMCIA ethernet because I still have a card or two in my basement, but who knows what crap you have.
Really, though, I just want to say thank you to the poster for a problem that Slashdotters really care about.
If any of you kiddies are interested in technology the NSA will have trouble getting at, I know of someone with a Contura laptop to sell you...
Shannon's theorem is true for a single channel. Eventually, cramming in more bits into one channel becomes power-prohibitive, because one must double power for each new bit added in. The benefits from adding power diminish even further when a system is widely deployed, as power from one system shows up as noise in the next, and SNR in all systems hits an interference limit.
To get around these limits, two related techniques are used
1) adding more antennas, to create more channels which are separated in space
2) coordination techniques that reduce interference from one spatial channel to another
If 2) is done well, then 1) can provide the kind of linear benefits you'd hope for - each new channel contributes its share to the sum data-rate. As you might imagine, building very parallel radio systems and coordinating what's sent over them presents its share of challenges.
For those of you looking to try it at home, there is at least one Software Defined Radio platform that will drive the ~1000 spatial streams you would need for this:
