Front-End Editor for Wordpress Metaboxes

I am currently creating a frontend editor for wordpress using TDO Mini Forms an开发者_StackOverflowd I was wondering if there is a way to post values from a frontend form to a custom Metabox? I am using the wpalchemy metabox code.

Maybe one of these could be of assistance? Tutorial on editing post data from front end.
