wait a significant time. you now have a uml image installed. you can start it with
./linux th0=tuntap,,,''ip-of-your-host-machine'' ro
you're done.

+If you receive the following error when trying to start your uml process with networking:
+
+Exec of 'uml_net' failed - errno = 2%%%
+tuntap_open_tramp failed - errno = 22%%%
+SIOCSIFFLAGS: Invalid argument%%%
+
+I tried EVERYTHING to get rid of this. Finally the solution was VERY simple. Run as a standard user, who is in the uml-net group, and not as root. Note: This is a "works for me". I still don't know why this solved the problem, only that it did. Also, another oddity is that AFTER I had run it as a user, I could then run it as root with no problems. This smacks of tap0 being created with incorrect permissions or some oddity. Anyway, it works now.
