I got a good deal on a Junebug which I hope to get soon. I'm curious if you can you reduce the +5v to +3.3v to program 3.3v targets? Is it more complicated than that?

Was that you I was bidding against on Ebay? I didn't try too hard. Already own one...
As is, the Junebug won't do 3.3V. That part got cut out to keep cost/complexity down. The original PICkit 2 has the capability. Bill is playing with ideas for a mod for Junebug so it can do 3.3V.

Probably
It was for a pre-built one with green LEDs. I was going to buy an unassembled kit until I saw the auction. Even though I like to build, I couldn't pass up bidding on it. Bill being active in the community is a big plus for the Junebug over other programmers. Missing out on 3.3V PIC isn't a big deal for me right now.
I'm hoping to build a Freq counter and LC meter using PIC in the future. I need them to support my radio projects.
Unless you need the 3.3V stuff it'll do everything a genuine PK2 will do. If you want to dabble in high end PICs the many 30Fxxxx are 5V.
You can also hook a PK2 or another Junebug to the Junebugs 16pin header and use your Junebug as a USB experimenter.
Remember, the voltages are controled by the software onboard the 18F2550. Comes from microchip. Unless he puts all the stuff (or most of it) that he left out you can't automatically do it.
To see what he did vs a real pickit2, go to microchip's web site and get the doc on the Pickit2. At the end of it is the schematics of a "real" pickit2
