LabVIEW
Is LabVIEW based on NI-DAQ ?

There is no NI-DAQ for Linux. NI used to have some beta software called
EDAQ which could be used to interface to E-Series DAQ cards similar to
NI-DAQ but their current approach is to use the RLP (Register Level
Programming interface) you can find on their site. In the future they
have plans for a Basic (as in not full featured) DAQmx for Linux.

I don't think they still have the EDAQ driver available as it is
supposedly superceded by the NI Measurement Hardware Driver Development
Kit aka Register Level Programming RLP.
If you want to have more high level support the way to go on Linux is
using the Comedi library which supports most of the popular DAQ devices
from NI.
DAQmx for Linux is probbably not yet available. I have no idea when NI
will make this available. Your only option in regard to this is
inquiring with NI directly by trying to register for a possible Beta
program if there is any. Please be aware that attending Beta programs
means testing software which is likely to crash sometimes and it may
still not support the functionality you would like to use.

Comedi never will be ported to Windows I would assume. Its
architecture is very Unix centric and porting to Windows
would be basically impossible without a complete redesign.
Comedi will be improved with new support for sure and it
will only get more stable if users are using it and providing
feedback and bugfixes.

There are two options for you. The NI Measurement Hardware
DDK is supported on both Linux and Windows (and some other
systems too including MacOS X and the NI realtime platforms).
It is the low level and I mean "low level" API you
are probably
talking about and is basically the same on all platforms it
supports.
Another option might be to look into UEI as an alternative.
Their hardware has Windows and Linux drivers which I would
assume have the same API.
> By the way. OpenG do not concern to low level.
No, the OpenG library is a LabVIEW VI library to interface
to the Comedi library which handles the low level stuff.
It is possible to write a VI library which might call Comedi
but is for the rest compatible to the NI-DAQ VIs.

No, LabVIEW is a paid software license, Linux or not.
