Arduino as ISP?

Is it possible to use a Uno as ISP to program a pro-mini using the web-based arduino create?
This is how I program my pro-minis using the regular IDE. You have to select 'Arduino as programmer' in the tools menu - but I can not find a similar option in the web IDE.

Thanks in advance for any help.

Not yet at least.

You might want to add that to the wishlist thread as other boards and such are a common request.
