What's it take to go from a double to a triple crank on, let's say, a Cannondale R3000 with DA components?

You need to change the crank, BB, front derail, and rear derail to accommodate the triple. Kind of a pain and costs about $300 for all Ultegra components. Another option you can do is get a mtn biking cassette (eg: 12-32 mega drive) and rear derail. This keeps the bike a double, shifts faster, and doesn't add as much weight. It is also very easy to change back compared to using a triple. It works great and costs less, usu less than $100 for XT level but more obviously for XTR. Some use this for cyclocross.
Only $300?like2bike

I think it would cost more than that. Going with the double and a 12-32 cassette will work if your rear cage is long enuf, but you might also need to add a couple links to your chain. The surprising thing is that you get amazingly close to the same low end with a 39x32 as you would with the 30x25 on a triple. Your shifting pattern isn't as tight, though...

Older DA 9 shifters won't shift the triple up front. Now you're looking at more cashish for a new lever (or just the guts).

Hey, you've got DA, toss a 12-27 and a few links in and suck it up and save your $$$$ - assuming your knees and legs are good. ;-) Sometimes I wish my gearing where a tad lower, but this combo works on most of the brutal pitches out NorCal way. The Terrible Two is a horse of a different color.

I went throught the same thought process, ie; upgrade to triple?, when I found out my 59 year old legs wouldn't power my Dura Ace equipped bike up our many (!) and big hills we have here in eastern Washington. The cost of switching to a triple set up was far too much.I wound up installing an XT rear der and 12-34 cassette. Now, I may be slower up hills but I can make all of them. The only downside seems to be that when I get passed by younger faster guys they eyeball the rear of my bike funny.

Neither will the new ones, according to a shop owner over in rec.bicycles.tech. There will be a specific front shifter for DA triples, and the shifter is not currently available outside of the set.

FWIW, the latest issue of Cycling +, a UK magazine, has a complete test on all the components in the DA Triple gruppo.
