Assign capability to edit specific plugins only?

I realize that WordPress 2.0 has 5 predefined Roles, each with specific Capabilities. It also states Plugin developers will likely revise the ‘standard’ Roles and Capabilities because WordPress Developers left open the future possibility of assigning a user to one or more Roles, or assigning Capabilities directly to a User. This is quite interesting, and I wonder if something very specific is possible.

Can a user be assigned the edit_plugins capability for specific plugins only? For example, let’s say I have 4 plugins installed called A, B, C and D. I have an Editor, and I want that editor to be able to edit plugin B and only plugin B with no ability to edit A, C or D. Is this possible?

Thank you.
