Forcing an application to specific Network Connection... AGAIN!?

I have a laptop on my desk just for testing external access issues to our sites. I'd rather not.

I know it's been asked.. I think I've read over 20 posts on it with no clear and simple solution.

On my windows7 x64 station I have a hard wired LAN Network Connection and a USB wireless network conection. If both are up, IE uses the wired Lan connection. If I disable that LAN connection, IE uses the wireless. Great.. but?

What If I want to have both up? Reading emails and and accessing other intranet resources normally, but surfing via the wireless. Or even better, surfing from a specific browser or instance of a browser through the wireless Connection, and all others using activity through the wired Lan connection?

I'd like to do this without a Proxy or a VM. I understand there is a product called ForceBindIP that sounded very promising, but it does not support Windows 7 yet.

Is there maybe a firewall setting to route port 80 and 443 traffic to a specific Lan connetion? How about tweaking setting of the wired lan connection so that it fails to find DNS servers or anything on the outside?

I'm somewhat surprised this is not a setting somewhere already. I see great value having this.

Thanks.

Cisco has a software that can do this but I'm not familor with it and don't know much about it,you might even need a Cisco router to use the software.
