Actually it is possible and very easy. Here is my setup:
linde (home machine) 36.92.0.118 running Marble SLIP as client
physics (machine at Stanford U.) 36.92.0.18 running Marble SLIP as server with du0 (slip0) ip address=147.135.1.184
elrond (another machine at home which is connected to linde using ethernet) 36.92.0.19

Here are routing tables for linde:
linde> netstat -rn

Notice: 36.92.0.19       36.92.0.19 means that when linde wants to connect to elrond it will not use the default route to physics (147.135.1.184) but instead it will use 36.92.0.19 thu en0 (ethernet).

On both linde and physics I have the file /etc/resolv.conf contain the following
domain stanford.edu
nameserver 36.56.0.151
nameserver 36.21.0.20
nameserver 36.8.0.47
It specifies my domain and the nameservers to use. Make sure you have something like this otherwise you will not be able to connect to hosts by name rather than ip address. (you must get your own nameservers)

Now, on physics I have to use arp command. Here is the command I use in rc.local
sleep 15;arp -s linde 0:0:0f:00:9b:00 pub&
This will advertize linde to the local net.


The result is that from linde I can telnet (or connect in any other way) to/from any other Internet connected machine in the world. From linde I can also connect to elrond by simply
telnet elrond
(elrond and linde and physics are defined in NetInfo database so it does not have to find out the address of elrond. If it did try to find out the address of elrond it would not get 36.92.0.19 from the nameserver, and it would probably get 'host unknown')
And it works!

Also the -NXHost from physics to linde works perfectly:
physics> Date -NXHost linde
This makes the Date application pop up on linde and lets me use it. (It is however slow...)
