IRC Integrated Chatbox?

[Nightfoxx121]

Hi, I was wondering if there was any kind of chatbox that could somehow connect to an IRC chat which is integrated to vbulletin?

Or atleast something alike. The purpose is to avoid lag that the current chatbox has and not having to split to two chatboxes.
I am currently using MGC Chatbox Evo but it seems that this chatbox tends to get laggy (by which I mean that it only refreshes every 5 seconds, and even if I lower it to 1-2 seconds it still remains on 5 seconds or 10 maybe)

Or if there is some kind of java/flash chatbox which doesn't lag like that but can integrate with vbulletin would also be nice.

Thanks for helping in advance,
Nightfoxx
