I like "Felix" a lot, so +1 from me. That's my first preference, but seems like there may be some conflicts with the name though that may be problematic.
In the event Felix is deemed unsuitable, I think elemental names for gases are catchy and just sound cool -- particular the inert gases. Examples... Nitrogen, Argon, Xenon, Krypton, Ozone, Neon, Radon... (Oxygen is already taken by an OSGi-like framework). I don't know... just throwing something out... I prefer Felix, though... -tbennett
