Re: [smarthome-dev] Requirements

[Benjamin Cabé <benjamin@xxxxxxxxxxx>]

Hi,

+1 for Compact 2 profile. This actually brings me to a question: OpenHAB, which I see (rightly or no, you tell me), as sort of a reference integration of SmartHome, uses Apache Karaf, which requires compact3, AFAICT. Would it make sense to maintain a lightweight, Eclipse Equinox-based, minimal SmartHome “distro” as part of ESH repo, that would be very similar to the openHAB demo setup, only it would be meant to show “pure” Eclipse SmartHome stuff?
Unless I’m mistaken, although ESH "is not a product itself, but a framework to build solutions on top”, it still has all the bits one needs to run a fully functional (yet limited) smarthome box, right?
