Well, as far as your wish list goes, I second the motion... But you'll find
that if you wait for Sun to do them...  well, nevermind...  <grin>

However, I've found an EXCELLENT alternative to PC-NFS' telnet.exe and a
tn3270.exe program...

Try using the clarkson drivers.  This means that instead of having all the
PC-NFS drivers in your config.sys, you'll have a few less, substitute a 
couple of the clarkson's and WALAH!  You can still have PC-NFS compatibility
as well as ALSO having the Clarkson NCSA TELNET, CUTCP TELNET AND TN3270!!!

My config.sys before clarkson:

	device=pcnfs.sys
	device=sockdrv.sys
	device=vecie6.sys
	device=?????.sys

After clarkson:

	device=pcnfs.sys
	device=sockdrv.sys
	device=pktd.sys

And my autoexec.bat has to also have this with clarkson's drivers:

	3c503.com 0x7e 5 0x300   (for my 3com board)
or
	wd8003e.com 0x7e 5 0x300  (for a western digital board)

And there you have it...  the clarkson equivelant (sp) for the sun hardware
drivers...

(you can find all these drivers on the clarkson "sun" and "omnigate" ftp
file servers...  128.153.12.3, 128.153.4.2, 125.153.4.10, I think...)

Also, here's a little PC source, for compiling with the Microsoft C PC-NFS
toolkit, to give you an "rdate.exe" function on your PC:

---Cut Here---
/*
 *  rdate - get date from remote machine
 *
 * 	Copyright (c) 1988 by Sun Microsystems Inc.
 *
 *     	"rdate" sets the date and time, obtaining a timestamp froma
 *	network host via the tcp/time socket.  Since this returns
 *	a value in seconds since Jan 1, 1900,  we must
 *	subtract 86400(365*70 + 17) to convert this to the time
 *	since Jan 1, 1970. (Note that to avoid Microsoft C 4.0
 *	compiler glitches we must compute this at run time.)
 *
 * This program is supplied as an example of how to use the PC-NFS
 * Programmer's Toolkit to port typical socket-based network applications
 * from Unix systems to PCs running PC-NFS and DOS. It is supplied
 * "as is" with no warranty or support.
 *
 * The binary (rdate.exe) was built using Microsoft C 5.10 and the
 * "small model" Toolkit libraries using the following batch file:
 *
 * cl /AS /Ox /Ze rdate.c ;
 * echo rdate + > lf
 * echo ..\toolkit\tcpypobj\syp_rtns.obj ..\toolkit\tcpypobj\sprotrtn.obj >> lf
 * echo rdate.exe >> lf
 * echo rdate /m >> lf
 * echo ..\toolkit\slibtk.lib >> lf
 * link /ST:16384 @lf
