In a previous project a couple of guys did just that. C++ compiling on ridiculously slow Sparc workstations was not fun, so checksums were made from the sources and object files were reused. If I remember it correctly, the speed gained was not that much as we hoped for and sometimes strange things happened - but this was 10 years ago and my memories could be wrong here. Faster CPU and disk was the real solution.

ccache to the rescue... almost invisible, works like a charm (only got bitten when crashes left empty .o files lying around, which ccache deemed correct...)
