curlopt_interface options in Curb?

[matthewvb]

I was told Curb might help me out as I transition a PHP app to RoR.
I'm trying to find an equivalent method of setting the outgoing IP
address for a cURL call. I was trying to using open-uri, but it seems
no such method exists.

In PHP, I was using: curl_setopt and passing curlopt_interface.

Is there a similar method in Curb?

Thanks!
