the double fianchetto is extremely unusual there; generally White only plays this way when Black is already committed to ...d6, e.g. 1 b3 e5 2 Bb2 d6 3 g3.

but ok, 1 b3 e5 2 Bb2 Nc6 3 g3!? d5 4 Bg2 and now you need a scheme of development. perhaps it's simplest to think of this not as a Nimzo-Larsen but a reversed Modern Defence (with a rather passive queenside fianchetto for White); and then think about reversed set-ups against the Modern; e.g. 4...f5, 5...Nf6 with ...Bd6 and ...0-0; or 4...Be6, 5...Qd7 and possibly ...f6, ...g5 and ...h5.

1...d5, 2... Bg4 with the idea to play a slav-like setup with the light squared bishop outside the pawn chain is something you can play against unusual white openings.

If h3 then Bh4, when white will probably play Nf3 soon anyway and the bishop will look less vague. If your opponent goes ahead with g4 (after h3), then a later h5 by black will undermine whites kingside, so white will have to be careful with his king.

The triangle of pawns e6, c6, d5 should be solid enough for you to withstand the pressure of a double fianchetto.

One line that I have been having trouble with recently is the Nimzo-Larsen attack.  Specifically, most of my opponents tend to fianchetto both bishops right away.  So far, most of the openings start like this:

1. b3 e5
2. Bb2 Nc6
3. g3 d5
4. Bg7 Nf6

I usually follow up with putting the bishops on e6 and d6 and trying to castle.  Fritz seems to favor this method.  However, even when playing against opponents who are slightly lower rated or about equal, I usually lose at least a pawn due to the long term pressure of the fianchettoed bishops and strikes at the center.   

So I was thinking about other ways to combat the Nimzo-Larsen.  Does this look like a good system?

1. b3 b6

This stops white from fianchettoing his other bishop immediately and seems flexible.

2. Bb2 (or Nc3 or Nf5) e6

This allows a later Nf6 without fear of getting doubled pawns 2. ... Nf6 3. Bxf6.  I know that white is losing tempo and the bishop pair, but black's pawn structure looks ugly after the trade.

After these moves, possible follow ups would be 3. ...Nf6 and possibly even 4. ... g6 5. ... Bg7 6. ... 0-0.  Although after move 2, the ideas could vary depending on what white does.

I haven't tried this system in a real game yet and I couldn't find very much information on it.  The system seems like a queen's indian type of setup.

I was wondering if anyone could tell me if this is a good way to meet the Nimzo-Larsen.  Any tips on meeting the Nimzo-Larsen would be appreciated.
