What is the situation in this respect?
The 32-bit limitations are on things like the size of individual files and IPv4-only addresses. The kind of information that is sent back and forth between Coda clients and servers. The memory address of some internal file object is never sent across the net, so we can just use whatever pointer values the local machine uses, which can be 64-bit. Jan
