This plugin looks great. My post on controlling custom fields with theme code (http://sltaylor.co.uk/blog/control-your-own-wordpress-custom-fields/) is very popular, so I'm sure you'll get a lot of interest.
I'm about to install thisand see if it might replace my own system - there's already things I can see that beat mine hands-down. The one thing I'm wondering about is permissions. Is there a way to limit access to the field to certain users (e.g. by selecting a capability that's needed to access the field)?
