It's not that multiuser is impossible using KLH10 networking emulation

SIMH virtual multiplexer. Wifi (under Linux at least) doesn't play all
that well with bridging and virtual networking stuff, which makes
setting up networking in KLH10 nigh impossible for those of us stuck on
wireless. I can't even really set up a VM and run KLH10 in a guest,
because Virtualbox's bridged mode doesn't work for me. Additionally, the
idea of putting anything running a 30 year old TCP/IP stack onto the
Internet scares me, even if the folks at twenex.org <http://twenex.org>
have done so.
The WiFi problem is easy to solve. It's called a router. Your host
routes IP between the WiFi interface and the virtual network the host
and your virtual machine shares.
Trouble setting up networking on the virtual machine? Maybe. But this
boils down to - if you want to run that host, you should learn how to
manage it.
Security issues are mostly non-issues. How many script kiddies today
even know what a TOPS-20 host is. There are most certainly
vulnerabilities, but they are very different from the ones presented by
modern machines.
I have an RSX system on the Internet, and it gets constant probing over
telnet and http, but they are all probing in ways that just don't make
sense. So I have never felt more secure.

If the recently promised release of Linux code for DECnet/LAT
materializes, you'll be able to
connect to KLH10-based machines with as many connections as you
can keep
track of.
Both TOPS-10 and TOP-20 on the KL supported LAT, and of course
DECnet
NRT and CTERM.
...and telnet. So, (as also Rich pointed out), what is the problem
actually? Are people so limited in their mind that they only think
that they can use telnet if the simulator have a telnet to serial
port connection, and do not think that the OS itself actually can do
networking... (with many different protocols)
