It would be nice to store some of the numbers on the hard drive(s), i.e., use the disk(s) as virtual memory. Because accessing the disk through the C++ functions and the kernel might be very slow, it might be best to purchase additional disk(s), and to program them directly in assembly language, bypassing the kernel. This can expand the size of numbers by at least 100X.

GMP's source is available. Feel free to write all that stuff you propose and send it in as a patch. Then watch your patch be tossed to the trash, for reasons that have been discussed often on this very mailing list. From the looks of it, you haven't tried searching the archives.
