Also, how much need is there really to do things remotely? I would think most people (not the DIY person) would use that occasionally if at all.
In my entirely personal and I've been wrong before opinion, I think that's because it's not easy with pretty much every other package except CQC to even do things remotely. (and again, I discount webserver remote control as it's not wife-usage or IVB-coding-ability-friendly).
As an example, over the years my wife has questioned:
1) Need for a 2nd PC
2) Need for a laptop
3) Need for a wireless network (In 2002, the woman would walk around with a laptop that had a 50' ethernet cable, thought that was "ok")
4) Need for a network-enabled printer (so the office PC didn't have to be on)
5) Need for Quicken and online downloading of our financial transactions
6) countless other things
That is, until she got used to the convenience. Now that she's used to #1-#5, there's just no chance in hell she'll live without it.
I'm confident the same concept applies for remotely controlling your house. I've pulled up the security system darn near daily in the past few weeks:
1) to see if the wife is home, cuz she's not answering her cell or the house phone and we're trying to arrange for logistics for roughly 19K random events in the next month.
2) Wife asked me to check on who called last night as we were expecting an important call and the dimwit hadn't called us before we had to go. (the extent of our phone integration - if we had a message, we'd just call the house and retrieve it).
3) Disarm the security system so one of our "less than intelligent" friends could go get something from our house (he has a spare key) without tripping the alarm like he did last time.
4) Start a DVD for the babysitter who barely understands how to turn a TV on. She's smart enough to put a DVD in a drive, but I swear the teeny-bopper is baffled by the concept of a stereo system, and I weep for the future.
I personally believe that remote control of your house is the future, the only question is how much are you going to fight it, and whether it'll be like instant messaging and text'ing, where only the young'uns do it and the old farts refuse to do all that fancy stuff.
