Wow those voices are impressive!
I'm pretty much in the same boat as ozanam although there are quite a few points less on my list =)
But really all I think I need is the Bluetooth and the space for external USB storage. The reason being so that as I walk around my house with my phone I realises I enter a room and TV or music follows me or even just to use my phone as controls. I plan to use wireless pads (Orbiters) for all the controls in the house 2 maybe 3.
I was also interested in the part where the system follows you as you walk into different rooms. According to the wiki (http://wiki.linuxmce.org/index.php/Follow_Me
) it doesn't work too well as, well, bluetooth is strong and works decently through walls. It states "...when the MD your moving towards can sense your bluetooth signal...", does this mean 'No Signal -> A Signal' or "Weak Signal -> Strong Signal'?
One thing about ZWave, Insteon, X10 etc. is also availability. Especially for things like Z-Wave I would say it's much easier if you live in the US. I live in the E.U. and, unless I'm bad at searching, the range of products available for Z-Wave is quite small.
About having a fingerprint for your door. I hope it wouldn't be the only way to get in the house as it could be quite troublesome if the system is down for whatever reason
Quite nifty none-the-less. I had in mind something else (if it's possible) for the greetings. Basically as previously mentioned bluetooth is strong and will most likely work a bit outside the house (at least mine). As soon as you come near the house LMCE will detect your phone and it will greet whoever's phone it is the next time the front door's sensor gets triggered.
Of course, if it's possible, it wouldn't exactly be perfect. You often come home with your family so maybe there are more than 1 phone getting detected etc. Bluetooth is rarely used outside the house so it is most likely off as you walk in. This would mean 2 things. First you won't be greeted as you walk in (not the end of the world I know ^^). Secondly, when you turn on the bluetooth later, as you're inside, the system will be waiting on someone to trigger the door sensor (maybe a time-out thing could be added, I don't know, I have yet to see the event administration). In any case, the phone is the only "personal ID" for the system that I can think of.
