Given that LDC is going to be released any day now, and should support 64-bit, any
estimates of how long it will take for LDC to support D2?  I work with huge
datasets and occasionally run up against the 2 gig address space barrier of 32 bit
on a computer with 4+ gigs of RAM.  Therefore, I for one would really find such a
thing useful.
