<DT><B>Parameters:</B><DD><CODE>domainbus</CODE> - a domain of the form 10.0.0:1234, it is similar to the
netmask without the trailing .255. This will determine the meeting point
of the different applications. Right now, this is done with an UDP

<DL>
<DD>Subscribes to a regular expression.
The callback will be executed with
the saved parameters of the regexp as arguments when a message will sent
by another agent. A program <em>doesn't</em> receive its own messages.
<p>Example:
<br>the Ivy agent A performs <pre>b.bindMsg("^Hello (*)",cb);</pre>
<br>the Ivy agent B performs <pre>b2.sendMsg("Hello world");</pre>
<br>a thread in A will uun the callback cb with its second argument set
to a array of String, with one single element, "world"<DD><DL>
