It sounds like what the OP does is put the IC in an ice bath, then run the wort through the IC, as opposed to putting the IC in the hot wort and running the water through the IC.

Here's a thought:
Step 1: put the IC in the wort at knockout, then run tap water through it to get it down under 100F
Step 2: run sanitizer through the IC
Step 3: put the IC in an ice bath and run the wort through the IC into a fermenter

That should get it plenty cold enough and doesn't require any additional equipment.  You'll have to play with the flow rate and how far below 100F (if at all) it needs to be before you run it through the ice bath to get the temp that you want for pitching.  You can do a trial run with water first so you can be in the ballpark your first time through.

I still want to know how you control fermentation temps though. :)

Tom,  

To control the fermentation temps I use a swamp cooler with an ice bath to keep the fermenter cool - approx 65F.  The swamp cooler isn't all that effective due to the high humidity here in S.E. Asia, but the ice bath helps, and I keep it all in our guest room with the A/C cranked.  So, I think I'll set the carboy in the ice bath (after using the IC to drop the temps to at or below 100), and pitch when the temp is down to below 68F.  I'll see how long that takes, then maybe for the next batch I'll purchase a pond/utility pump, per hopfenundmalz's suggestion.  

Thanks to all for helping out a brewer a long way from home!

Ice is a really effective (and quick) way to chill the wort if you're doing a partial boil, too. Or even if you normally wouldn't be, but are willing to cut your boil volume slightly. If you can chill 4.75 gal to 95°F using the IC and then add 0.75 gal of (pre-made sanitary) ice, it'll stabilize at about 63°F.
Beer is like porn. You can buy it, but it's more fun to make your own.

Sounds like a plan!  The one thing you might want to consider is to cool it closer to 60F before pitching.  Pitching colder and letting the temp rise slightly is generally accepted as a better process.

Sounds like you would benefit from a small used fridge with an external controller....... in fact, if you keep it clean and sanitized it would be a perfect place to park the brew kettle for a while after you get it down to 100º.... A lot less hassle, and better control.
