It appears that the IBM developers in Boeblingen are actually working on 
something like that.  Recent updates to the development trees on the git390 git 
server have been mentioning an "HVC":

[S390] s390/hvc_console: z/VM IUCV hypervisor console support

This patch introduces a new hypervisor console (HVC) back-end that provides 
terminal access over the z/VM inter-user communication vehicle (IUCV).

The z/VM IUCV communication is independent of the regular tcp/ip network and 
allows access even if there is no network connection between two z/VM guest 
virtual machines. The z/VM IUCV hypervisor console back-end helps the user to 
access a z/VM guest virtual machine that lacks of network connectivity; and 
thus, provides a "full-screen" terminal alternative to 3215/3270 terminal 
sessions.

Use the hvc_iucv=[0..8] kernel boot parameter to specify the number of HVC 
terminals using a z/VM IUCV back-end.

A recent version of the s390-tools package is required to establish a terminal 
connection to a z/VM IUCV hypervisor console back-end.



It's not upstream yet, but I imagine it will be in the not too distant future.
