Hi, it should be since it will compile to native code (doesn't have to run through an interpreter). That being said it will still chow battery until I can get it to stop intelligently.
Am in the process of coding up an early version now, hopefully it will be ready for early testing in a few days time. Also, since I am coming from a Windows/.NET background it will take a bit of fiddling to figure out how to get a list of running processes (looks like I'll have to make use of /proc) but once that is done it shouldn't be too hard.
May also consider making it have some DBus calls so you can pause it or start it using a shortcut or something on your desktop (you could call the lock thing anyway when you do so just to prevent them from doing it themselves) which would prevent it from sharpening its claws on your precious battery

Will let you know when I have something to show for it.
