Embeddable Forms Network Wide


Can anyone recommend a plugin or soultion that provides the ability for a network admin to create an embeddable form that can be placed on all subsite in the network for the purpose of collecting data submission from users on the subsites?

Perhaps a plugin that generates allows creation of a form and then generates the form's embed code that could be placed in a widget area on subsites?

I am familiar with and frequently use Google's embeddable forms, (great solution!), but for this application we are looking for a solution that adds the form data to tables in the Wordpress database rathter adding it to an external databse.
