large waveform file support?

I have read a great deal recently on how to write/read large files in LV. Unless I am missing something, there doesn't seem to be a clean "native" LV implementation of large file i/o? OpenG has some vis that do the trick for Write/Read Bytes to/from File, but I need to find a way of Writing/Reading Arrays of Waveforms to/from a file of perhaps up to 50 GB. Currently, even though the record number input on the Read WF from File vi is an I32 (leading me to think I can have a really large number of records!) there appears to be the same 2 GB limit as other native LV file i/o vis. Has anyone solved this issue (writing and reading arrays of WF to "large" files)?

Managing large data sets in LabVIEW has been othen discussed in Info-LabVIEW, but I think this NI-link could help too:
