Hi Chris,

euTCP4u (and TCP4u as you mention) can't handle this.
In C (or C++) this is overcome by using threads which Euphoria doesn't
have.

If you have full control of the Server and Client software you can use
euLibnet. euLibnet has a polling mechanism which allows multiple
connections to be running at once.  The down side is that it is 
only of use if the server using the Libnet API's.

If you don't have access to the server side than I think the Euphoria 
Sockets wrapper is your only choice.
