スクリプトを用いて似た機能が実現できますよ？
以下、簡単な例
----
function event::onSendingCommand(command, param, context) {
if ( command.match("(HTTPS?://[-_.!~*\'()a-zA-Z0-9;/?:@&=+$,%]+)") ) {
var url = RegExp.$1;
var req = new ActiveXObject("Microsoft.XMLHTTP");
if (req) {
req.onreadystatechange = function() {
if (req.readyState == 4) {
var s = req.responseText;
if ( s.match(/{"short_url" *: *"(https?:\/\/[-_.!~*\'()a-zA-Z0-9;/?:@&=+$,%]+)"}$/) ) {
sendRaw("PRIVMSG " + selectedChannel.name() + " :" + RegExp.$1);
}
}
}
url = "
http://ggl-shortener.appspot.com/?url=" + encodeURIComponent(url.toLowerCase());
req.open('get', url, true);
req.send('');
}
}
}
