this is realy wrong

in most msn, yahoo, aim clients you can change the port to use. for example yahoo client uses a wide port range, and a wider ip range. so this time of port filtering is realy unusefull. And I am not talking nonsense- I was involved in this tipe of filtering. Realy, the only application-based usefull filtering is proxy, but that becomes also unusefull when coming to online-3rdparty clients, wich are not few, and also come with many mirros. The best option seens so far is using internal instant messaing, wich keeps users busy with chating eachother internaly, and maybe talking business :) .
