To be able to embed LJ2 into a 64-bit application would really help us.

Also, can you elaborate a bit more on what effect we should expect if
LJ2 would use 64-bit-specific features? Would it run noticeably
faster, for example? (Sorry, that was, probably, already discussed; a
link would do.)

Excellent news!
