sounds like rsh's (ssh) and bla bla bla "cut"

OH, now I getit.
Ken, (you brutalized me over this shjt, you know)
Have the guest do an ifconfig () locally, and ed (1) just 
the IP address. Since it's a virtual, it will have a :nnn suffix
on the IP.  Strip off the :nnn to get the root IP of the host OS.
If you actually need the (v)host's hostname, then issue
an nslookup (8) and ed (1) it from there.

There are probably other ways to pull this off, but this is
the one that popped ito my head  I used to run VMware on
a dual-celery tiger board, and I learned a buttttload about cajoling
these things.  Unfortunately, I shook the thing to nano-bits in a
UHAUL comming back to the triangle from Sacramento.
. 
Of course, your mileage may vary.   Am I making this to simplistic?
