I did think of Call channels, and had a good look at the docs on them, but I
found the way they're implemented in JCSP a bit hard to understand, and
being new to JCSP I decided to go with the simplest approach first.

I may well have another look at them. Have you any suggestions on further
reading or good examples of use?
