Couple of questions about Folder Permissions

[Raja Cobra]

Question 1:
Is it possible to list all the permissions (r, w and x) that a given USER (logged in user or other user) has on a target FOLDER?

Question 2:
Is it possible, for a given FOLDER, to list all the Users and Groups that have a particular permission (say, "execute") on it?

Appreciate any suggestions to help me with this.
