any code (C or asm) you write for the sparc line of CPUs will run on all sparc
CPUs. the only difference is that if you write it for supersparc then it
won't run as well on a lower sparc (microsparc) since there is a slight  
difference in the instruction scheduling.  i think making a general binary
for just the supersparc CPUs should run fine on all of the CPUs.  although
i wouldn't mind seeing a client that is optimized for my sparc5.

SunOS 5.5 binaries won't run on a machine running SunOS 5.3
SunOS 5.3 binaries will run (but not as efficiently) on a machine running 
 SunOS 5.5
SunOS 5.5 binaries may or may not run on a SunOS 5.4 machine, no clue, never
 ran 5.4 skipped it when we went from 5.3 to 5.5 (and now 5.5.1)

as long as you keep the SunOS version the same as what the machine runs these
binaries will run on any of the CPUs and pretty well at that.
