I guess the scarey thing is the reality presented to us in film, for
examplke the implants seen in Ghost In the Shell and other such movies are
all possible, there is a small quanity of silicon in the body which means
that a nanoprobe will be able to build a low voltage laser diode 
This is a possible interface which would work similarly to the way audio
equipment is interfaces with optical cable, the human body would be capable
of handling the sensory input but the wiring of circuits into the body
would me that we would have to take suppliment tablets to provide the
nessary metals to build such an array of microprocessors and details, but
where would you have this jack that allows you to be an onliner.
The other ramification would be the division between the people with
cybernetic jacks and the poeple without them, I am sure this would bring on
its own social ramifications which may not be needed in the real world. but
it is fun for sci fiction, for the moment.
So when do you think we will see the humble nanobot/probe being used in
such a way, well that still might be in the realms of science fiction or
maybe even closer to fact.
Anyway have a great day

and to you too...
if you want to dive deeper into the man and machine interface, check
out "Cyberpunk" and "Shadowrun" role playing game.. there's quite a
few rule books about cyber implants, bioware etc. That should really
get your imagination in overdrive. :-)
[...Followup posters are reminded that "game science" often has little relation
to scientific plausibility, and are urged to perform reality checks against
scientific and engineering literature before taking RPG rules too literally...

Recent work suggests carbon nanotubes can lase, or organic LEDs
lasers might be considered.

You would need an electro-chemical interface, to interact with
neurons, though existing systems seem to use just use electric
current to stimulate (I think) synapses. And pickup nervous
impulses for output.
We are some way yet from understanding how the brain processes
sensory input, but if you could piggy-back on the existing
inputs, and rely on the ability of the brain to learn and adapt,
you might get somewhere.
If you can build all the required bits from nano structured
carbon, you have all the raw materials...
Making sure you did not upset the immune system would likely be a
high priority.
As for interfaces, some form of electromagnetic induction which
avoids the problems of holes in the skin, or maybe even a laser
and pickup array, also operating though the skin, might work.
Could look like a tattoo...
All these things have appeared in science fiction.

There are issues of the expense of installing such interfaces;
just about anyone might be able to afford it (nanotech can
massively reduce prices). Then, there is the training to make
effective use of it, hopefully easier than learning to read!
Ghost in the Shell suggests that there may be big advantages in
not having anything more than the equivalent of a cell phone
implant; no one can hack your mind!
Also, the consequences of a operating system crash or viruses in
something connected intimately to your nervous system could be...
unpleasant.

As above, we need to know quite a bit more about how the brain
works for some of these things.
Then there is the question of how much a given human body will
tolerate in the way of bits it doesn't recognise running around
inside it, or connected to it.
Several breakthroughs are likely to be needed, and you can't
really predict these.
And, we don't know if nanotech will stall in the same way that AI
did, for twenty five to thirty years.
If we do get nanotech in ten years, which does look credible,
medical nano will be a high priority, particularly for people who
can't be helped any other way.
Crude interfacing will likely appear quite early, as people are
already experimenting with it using mesotech, but getting things
so that nanotech has the appropriate software to work in a
massively distributed way in a delicate and hostile environment,
without triggering something like a massive allergic response...
I understand there are problems at the moment of nerves that are
connected to, for example in those cyborged rats, becoming
insensitive over time.
Cheers!
