I cannot say with certainty whether VMIPS will "ever" be able to emulate
an SGI Indy. That depends, of course, on whether anyone will "ever"
do the work required. :-)

An Indy is a 64-bit machine, based (in its latest incarnation, if
I recall correctly) on the R5000. VMIPS emulates an R3000, as found
in the DECstation, which is a 32-bit part. So changing VMIPS to simulate
an Indy would entail significantly more work than emulating, say,
a different 32-bit MIPS part.

VMIPS can already do some rudimentary emulation of some DECstation devices,
however. See decserial.cc, deccsr.cc and decrtc.cc in the VMIPS source.

If you need something that simulates a full MIPS system today, you might
be better served by mips64emul, for example.
