lol reading your sig and wrestling!
Yep, integration with Instant Housecall (IHC) is something recently launched that we've been working on for a little while now with a bit of discretion. The entire point for me, is to gain more exposure for d7. That and also I'm using IHC myself, and I wanted to do some integration to make things a little more unique than you can get with the standard d7 experience -- like googling research initiated from d7 on the client PC opens the browser window on the tech's PC, instead of the client's PC; few other neat little things but that's my fav.
The caveats are that it is currently incompatible with existing d7 configs (though I need to work on an import process for people moving over,) and also config save/load is handled by IHC entirely, so dCloud is not necessary or compatible currently.
As for Macs, no that's an IHC thing only
Their remote support will work on the Mac -- but I think I can safely say that d7 never will...
I haven't heard of a live OS with d7 integrated, can you find that again? Referencing this might be a lot easier than coming up with a new guide to build a WinPE based tool with d7 already in it. (Personally, I still use any old WinPE boot disk, and just keep d7 on my flash drive plugged in, but I guess not everyone wants to operate that way ...) I'm also interested to see how they included d7, and if they properly copy it to the RAM drive or local OS drive to run, instead of trying to run it from the actual write-protected media (if disk is a CD/DVD)...
EDIT: and yeah, best deal is buying from me
IHC's 'Remote d7' will ONLY work inside an actual IHC remote session, and features are restricted to what can be done remotely. But it's nice to have options and the IHC version just makes for an easy one, even for those who already own d7.
