My friend and I are considering purchasing Apache-Havoc as well as Commanche-Hokum, she's really curious to know if we can both operate the same helicopter in multiplayer (Pilot and Copilot/Gunner set up), or if there's a mod that will allow us to do that.
AFAIK, unfortunately, no. LB2 stands alone in that capability.
Also, do the mods allow for cockpits and Track IR?
Yes. Cockpits are included and TrackIR works. Especially fun when using TrackIR with the Apache.
We'll be running both our simulations in Windows7 64bit.
Runs fine in 64-bit Windows 7.
