Monks; I have been away for some time on a forced excile to the land of Python; but have returned to the fold.

I am in need of guidance for the following. I am trying to use only core packages. I have taken the Msg.pm from "Advanced Perl Programming" (vol 1) and have grafted in a 'workproc' mechanism ala Xwindows. Now I need to be able to handle UDP packetes in the event loop as well as TCP. I am hoping someone has done that and would be willing to share.

There are some portions of the code I don't understand. The use of a data structure 'g-pkg'; and the following 

     #New Server
     my ($pkg, $proto, $my_host, $my_port, $login_proc) = @_; 
 
 and 

    sub set_event_handler {
         shift unless ref($_[0]); # shift if first arg is package name
         my ($handle, %args) = @_;

The 1st looks like all new_server call are always OO,
but set_event_handler() may or may not be associated with an Object

====Update:========================
As I continue to look at this (Msg.pm) code, the more I see what seems to be a single connection only functionality. 

sub _new_client {
    my $sock = $main_socket;

That is picking a '$sock' value from a global scalar ($main_socket) that is set only from 
$main_socket = IO::Socket::INET->new (

[download]
which is the last socket created. I am thinking that this may not be suited for multiple simultanious connections. If you look at 'g_login_proc', it is also a global singleton which is overwritten with each new call to 'new_server'.

So what are the recommendations for a robust communication and event dispatcher? (low learning curve is appreciated.

It is always better to have seen your target for yourself, rather than depend upon someone else's description.
