I have, but only with bluetooth, so distance is limited. And as fun as it was, it has no practical applications I can think of.
In this case, I did it with a laptop with a bluetooth unit.
I used a K750i phone as a remote commander, with a custom .hid profile so that the keys are mapped to the hotkeys of SManager.
You can do it so that you can engage datalogging without installing a switch, by using the handphone key to start datalogging on the laptop.
But like I said, not much in terms of practical applications, except the fact that I can use the handphone like a handheld hondata control unit, so I don't need to use the Ctrl-I, Ctrl-D hotkeys, rather I map keys like 5 = datalog on, key 1 = add fuel/ignition by one step, key 4 reduce fuel/igntion by one step (depending on what maps I'm in), etc.
It's pretty handy, but it adds a bit of complexity.. I STILL need a laptop. (>_>)
And I can't map one button to flip through the ignition and fuel maps, because hondata has 4 different shortcut keys for each of them.
Simple and I think most know how to do it, if they google it up,
I can post a short tutorial on how I did it (with pictures), if anyone is interested.
As for trackside tuning, I think it's doable, but there's quite a lot of equipment required.
1) carPC or equivalent, connected to a powered antenna to increase the transmission distance, running some form of remote control software (Remote assistance, anyone?)
There's better software out there, but for purposes of illustrating how it's possible (For testing purposes use the WinXP Remote Assistance, you can purchase better remote control software as you see fit), you can read it here.

I think one of the Wi-fi mags had an article where they boosted the internal laptop wifi antenna for further range. I forget how much range though, so maybe someone else can google it up.
2) trackside computer, connected via the same network through wi-fi to the pc in car, and running remote assistance, so the trackside computer can see the screen of the pc in the car.
Well, adding more weight to a track car I think is never a high point in anyone's to do list, so I doubt it's practicality.
The Innovate LM-1+Auxbox is a better choice for telemetry (with it's G sensors, MAP/IAT/etc depending on what channels you tap in or find useful), though you still need a carPC/laptop with wifi in the car in order to read them trackside. They do have bluetooth connectivity kits, but I wonder how practicality figures in their calculations.
Bluetooth is like only 100m's (AT BEST) so that's out of the question.. I did try LM-1 with Auxbox with bluetooth, but the range is too short to be of any use, apart from reducing cable clutter.

Nice, but I doubt you will find it useful as trackside telemetry tool.
