If you insist
Yes, but only in vehicles with no synchromesh. The technique is really the same as double declutching.
1. steady speed so there are no accel/decl loads on the transmission.
2. out of gear...this just works ok.
3. wait or touch the gas to get the exact speed of the crankshaft (rpm) matching the road speed in the desired gear.
4. into the new gear. there will 90% of the time be a crunch ranging from a light click to a few teeth hitting.
caveats.
DONT DO THIS ON A CAR WITH SYNCHROMESH ... modern "Porche type" synchros are not improved by this. Older "Baulk ring" synchros are even less improved by it!
ONLY do this on a car with straight cut gear wheels that are strong enough to take the strain. Something pre wwII may be ok! (Or a tractor?)

As long as you time it correctly, no problem at all, for upshift or downshift
I learned how to do this on an friends truck! Try driving a truck with 16 gears (4 for reverse).
Audi's are pretty easy!

Re: Has anyone ever shifted with out using the clutch.... Ive see it done in an eclispe... What woul
Yes I've done it on the A4 fairly easily with no grinding at all. I just accelerate get rpms around 4k or above and then when shifting just put slight pressure on the shifter.... when the rpm's hit the right number, the next gear will engage. If you put too much pressure, you will grind the gears. Don't force it, just let it fall into gear. For the first couple times, to find the right amount of pressure, if the rpm's drop too low, you may have to tap the gas to rev them back up. If my memory serves me correctly the shift point rpm is just above 2k rpm.
Downshifting is much harder for me, and I don't remember trying it in the A4. However, I had a Diesel Rabbitt, and I could easily upshift and downshift in that car. That was definitely the easiest car I've ever clutchless shifted.
I also had a clutch cable break in a Subaru XT. Drove it home with no problems.... Even through red lights. At the red lights, I had to turn the motor off, put the car in first gear, and then when the light was green, turn the starter. The car would move forward and start, and I was on my way. Luckily, I didn't have any lights on a hill, or I would have been stuck.... unless I started the car backward. :-)

Easy...
I Used to do it all the time on my jetta.
Upshift: put slight pressure on the shift stick into what ever gear you want to be at while you are raising the rev from about 2500 rpm. The stick should just "slide" into gear, you'll notice the resistance just disappear. Take notice of the rpm that this happens at.
Downshift: Pop the stick into neutral and blip the throttle to >3100 rpms...then push the stick into gear...This takes some more care....you need to know what rpm the engine wants to be at depending on speed and gearing...if you are going 40mph and want to drop into 2nd gear, you'd better blip the engine to at least 5k rpm...etc...

I used to do it in my old Celica, don't recomend it though....
I got good at it too. I would use the clutch to start from a stand-still and shift 1-2, 2-3, 3-4, 4-5 w/o clutch. Going back down through the gears was just a matter of matching revs. Takse a real delicate touch on the gas and shifter so that you disengage and reengage the gears when the speed/rmps are matched up.
I put over 110,000 miles on that car ('77 Celica GT hatch)(clutch @ 70k, I was the second owner and blame the early clutch death on first owner :-)).
Other 'fun' thing I used to do was launch hard in first to redline, jab clutch to floor, jerk shifter to second and dump clutch, all without taking gas pedal off the floor. next best thing to a sequential gearbox. Second to third was a bit more difficult.
Remember kids, don't try this at home.
