Yes, on the half-dozen or so routers that I worked on, the low delay bit 
was supported.  This was especially important for dial-up links.
(NetBlazer, Lan'sEnd, etc., none of which are in much use today.)

I have also _set_ the low delay bit for telnet traffic on those boxen,
but you don't telnet out of routers very often.

I'd have to check the source, but I'm pretty sure I put at least some 
of that stuff in Qualcomm/Sony cell phones and base stations, so it 
might still be in use today.

I have also used the TOS bits in a weighted fair queuing scheme.

I never figured out how "high reliability" would be implemented.  I just 
tried to never have low reliability. :-)
