I'm thinking that PC Condom needs to follow a 'Copy on Write' model.
But my thinking is that I don't need to persist changes to the hard drive but instead just write them to memory or at least virtual memory.
This will solve two problems with one stone.
1. a virus in memory situation
2. dicking with rolling it back problem
This will limit the product to a 4GB of changes, but that would probably be OK for most customers. I mean we're not talking about power users.
I like this idea. :)
