HIde certain plugins in "Premium Plugins" with Supporter

Hey guys,

I'm using Supporter with Premium Plugins enabled. The thing I'd like to do is hide a couple of my "auto-activate" for supporter plugins from the Premium Plugins page. In other words, when someone becomes a supporter, the plugin auto-activates, but they are not given access to deactivate the plugin. These plugins are necessary for their site to function as expected and I'd just rather not have them getting the option to break that - plus, it just makes things a little more complicated.

To further complicate it, I'd like to be able to do this on a per-plugin basis. I know I could hide the entire premium plugins sub-menu, but there are some that I'd like them to have control over.

Am I being too picky here? What's the best way to do this? I could add these plugins to the mu folder (as all blogs must become supporters if they want to continue after the free trial) but some of them are not written to be work from this folder. Thanks!
