Yes. Using the latest jackd1 release will make this easier, however,
you can also go for whatever your distribution has available.
Basically, you run
$ jackd -d alsa
on the first box and
$ jackd -d net
on the second. If you have jackd2, it would be "netone", not "net".
You then use Fons' zita-ajbridge on the second machine to connect to
your physical I/O. (they replace the older alsa_in/out tools)
The latest jackd1 can do the last two steps in one step.
Maybe netjack2 is also an option for you. Go for whatever works.

New subject: NetJack question
Many thanks for the reply, Adrian, this is much appreciated.
I don't have the zita-ajbridge installed so I thought I'd try the alsa_in
method first.
So on the first box, I run,as you suggest
$ jackd -d alsa
Then on the second box
$ jackd -d net
But then, when I try to run alsa_in on the second box in a second terminal
window, it fails and it crashes the jackd process.
I'm also wondering how I make the connection between the two boxes?
Here's a trace of box 2 (terminal 1):-
user@ubuntu:~$ jackd -d net
