I have heard that there is a serial interface in the dock connector, and good way to tap into that?

There is indeed, but (I believe) without installing Ndless, there's not a lot that you can use that serial port for.

In fact, this has been done in Lua, and it outputs sound through the serial port. But it was with another OS (I guess) and maybe the function that allowed to do that is no longer available. You might want to ask Nspire pros about that.
On OS 3.1, http://ti-pla.net/a4227 restores the Lua print() functionality, which TI needlessly removed and still hasn't put back to date (never will ?).

You are correct. It seems that the people deciding stuff think there may be security issues with allowing data to be send to the console. So yet another absolutely ridiculous idea from TI that only harms their users. I've had high hopes of it returning but well I was wrong. The education department is far too bloated to make proper decisions. HP is doing a much better job on that level.

Soldering on the calculator side (dock pins) is not necessary.
Then is the solution to find the mating connector (or a PCB) to mate to the dock connector, and solder onto that? I've also seen a solution that seemed to use a rubber band to tension wires against the dock connector. 
One thing to keep in mind, though, is that if you accidentally touch the wrong pin on the serial port when doing certain connections, you can permanently damage your calculator. This happened to certain people who tried the sound programs.

Yep, could see that. Justneed a good way to do this...

AFAICT, nobody has found the mating connector, and we haven't heard of the person who wanted to provide a mating PCB.

Neither critor's method (which can be seen in a number of TI-Planet news items), nor mine, require rubber band. We just take advantage of the dock connector's lid to keep the wires / modified 2.54 mm connector in contact with the pads.

It's a proprietary connector for the Wireless cradle like here
