FYI - my experience so far has been mixed:
1) i hate the fact they only allow drive level installation not partition based (maybe doing seperate installs of kubunto and the mce would allow more flexibility here, but the dvd-based quick install doesn't). I had to lose my XP install on the server just to try it
2) i'm basing everything here on the GC100 capability and so far i haven't had much luck. I got somewhere this morning in that whenthe IR lights flshed, i could see they were talking, i was prompted for a software upgrade, but i let it go for 20 min and it never moved beyond the "finding GC100" screen again). I'm going to reboot with the upgrade and hope for the best. However, skimming the forums, there were some posts that seems to imply i couldn't take advantage of plug-and-play for onkyo receievers and other rs232 based devices unless they are connected to a pc's comm port. I'm hoping mce treats the two comms on my gc100 as virtual and this still works - but can't find out until i get them talking.
3) So far i had to go with the "basic" gui which kindof is ugly. I have an nvidia nx8600GTS which supports opengl so i had hoped i could at least used the medium level overlay. Need to look into the drivers there and see if that's my only issue...
4) looks like elk is not one of the PNP security panels - that would suck as i'd be force to do the scripting
5) vonage isn't listed on the list of PNP VoIp providers - not sure if i have any options here at all
6) some of the pnp-support is iffy. For example, the panasonic model numbers aren't in sync with latest releases, but hoping the code is. And the way they list "Onkyo / Integra" i'm not sure if that means the integra had a a different protocol than the ones i have (hope not)
7) looks like lighting is pretty much proprierty zwave interface as they build it. I really want control through the elk+rxcop. I guess i could add a non-two way controller for this on the MCE side, but that's a bummer. or maybe run two RZCOPs and build the interface into it
8) oh and it doesn't seem to recognize my raid array (hardware based on the intel MB). Treats them as seperate drives (not good at all).
i keep chugging...
