Basically, you want to just stack spirit regeneration. Movement speed also helps the overall effect, but caps at 25%. Spirit regeneration rounds up or down, so make sure you have at least a .5 at the end of yours.
Passives you'll want: Fleet Footed, Transcendence, and Chant of Resonance
Follower: You will want to be using the Templar. With the inspire skill active (very bottom one), you will get additional spirit regeneration.
With this build, you actually regenerate more spirit than you spend, so you are free to use blinding flash, serenity, sweeping wind, etc. Stacking life on hit also helps out a lot when doing this in inferno difficulty.
So I just tried it because I was curious for a while and I had gold to burn: it does pitiful damage. Viable in Inferno? No (unless you want to Tempest Rush mobs to death for around 10x the time commitment compared to normal builds).
Other problems with it: it doesn't seem to proc LoH (I'm pretty sure lifesteal does work, but that swings back around to the fact that it does pitiful damage, so you won't be stealing much life to begin with), it doesn't proc Sweeping Wind (so that falls off), and obviously you're not auto attacking so the only damage you're doing is the pitiful 2k hit/3k crit off Tempest Rush (my regular crits were around 20k in my "Tempest Rush" gear set). So even if you boost your crit damage to 400%, your crits will still be pathetic at around 9k.
As someone who uses tempest rush in act 2/3 inferno, it is more of a defensive ability than offensive. When I first started using it, I was like "wow look how many times I'm hitting them!" but the reality is it does very little damage. Sweeping wind is basically a must when using it, and even then it isn't a huge damage dealer.
It is a good ability and I still use it, but I use it mainly to get out of surrounds or to do a lot of AoE to weaker monsters. I use the slipstream rune, so it is also pretty good for running through arcane sentries/desecration etc.
So is it viable? Possibly, but it is incredibly slow.
i tried this spell out at like lvl 8 on my monk, it says it does 50% weapon damage per hit but it seems bugged. when i was hitting for about 17, the tempest rush was still only hitting for about 2/3. unless im just majorly mistaken the ability is only dealing about 20% weapon damage. so ye, it sucks.

I used tempest rush in my main build with the rune giving extra speed. Its awesome for cc, moving fastly from a certain positions. Main problem with tempest rush is that it suffers from rubber banding worse than anything else in the game.
I experimented with tempest rush a fair bit and did not really see it as too much of a damage dealer.
I remeber when I first got tempest rush, i didn't know it was 'channeled' by holding down the button so i'd just twirl for a half second, and though to myself : damn this skill is totally useless!! But even after I figured out it was channeled, I felt Dashing Strike was 12 times cooler and more useful.
But aren't gold runs in NM nerfed to be fairly terrible now?
