Are you talking about floating at just to correct height to eliminate the vulnerable portion of her airdodge?
The idea is more to time her airdodge so that she avoids the attack and lands as soon as possible afterwards.... here I'll give an example frame map. Low floating Peach vs. Marth's fair:
Code:

1 1 [both characters land]
2 2
3 -[can now perform another action]

another action]
In this specific encounter Peach winds up with a +6 advantage over Marth; much better than shielding or spotdodging and about the same as power shielding.
Buuuuut yeah. I wouldn't be surprised at all if this turns out to be one of those "potential" things that, as -Cross- said, looks better on paper than it actually is in practice.
Too bad it's also ********.
New Peach AT: REVOLUTION
Anyways, this low-float airdodge, I played around with it a little today before trying to complete the SSE (I got a new replacement Wii): it seems slow.
:/
Yeah, Peach stays in the air waaay longer than I anticipated. For what it's worth here's some data showing how long she falls at specific float heights (includes the 2 frames of landing lag)
Float on F7: 10 frames (air dodge 1-8, landing 9-10)
... F8: 13 frames (airdodge 1-11, landing 12-13)
F9: 15
F10: 17
F11: 19
F12: 20
F13: 22 (air dodge runs out of invincibility at the end)
For the record floating on frame 7 of her jump is juuuust above the ground, but despite that it still takes her 8 frames to land from that height. Peach you floaty bugger you. So yeah, I guess if you're going to do this you want to be very close to the ground. Also she hits the ground much quicker when fast falling to airdodge:
Float on F7: 5 frames (1-2 fast fall, 3 air dodge, 4-5 landing)
...
Float on F13: 14 (1-2 fast fall, 3-10 air dodge, 11-14, landing)
...And you know, I hated the SSE when I first played it, but come to think of it I might enjoy it now that I'm more aware of the Brawl metagame. I wonder if the SSE fiends can handle pLaNkInG mEtAkNiGhT
