which ASP.NET hosting site allows listening on different ports than 80 and uses .NET 4?

I'm trying to take advantage of HTML 5 web sockets in .NET and the easiest way appears to be something like what this guy does.

I've already tested this myself and it works great, but there are a few problems if I try to deploy this to my hosting site (discountasp.net). Basically, I am not allowed to open up a port on 8080 and listen on it. I then tried to figure out a way to listen on port 80 with IIS as well, but using the HTTPListener, I run into sercurity issues as well. This doesn't seem like it will help since I can't mess with this stuff on the hosting site server either.

So to make my life easier, I think I need to find a hosting site that simply allows me to open up a socket on port 8080 and listen on it. Anyone know of one? Or does anyone know of a workaround (besides sniffing all the traffi开发者_如何学JAVAc on port 80)?
