Pre-render and cache embed.ly card instead

Would it be possible to have an option that renders an embed.ly card similar to what is output in the preview of this page:

http://embed.ly/code?url=https%3A%2F%2Fvimeo.com%2F126755949

Which takes:

<a class="embedly-card" href="https://vimeo.com/126755949">BOS->LAX</a>
<script async src="//cdn.embedly.com/widgets/platform.js" charset="UTF-8"></script>

and converts it to a fully rendered iframe?

The benefits are

• Really nice theme/design
• Responsive sizing
• Contextual information around media
• Share feature in upper right

The benefit to this filter as it was designed was that the returned HTML can be cached, and the regex works very well. Most importantly, WYSIWYG_filter never allows script or iframe elements from being saved, so the embed code from the example above (with the script tag) gets stripped out.

So maybe this is better off in a custom filter module, but wanted to see what others thought.
