I do this sometimes while i'm travelling, leaving a big project open on my home desktop, and then when i have a few idle minutes connect to it from my laptop and make a few edits. From a local network it's not too bad, but from elsewhere it can take 10 or 20 seconds for the screen to update so doing anything more than a few basic cuts or titling is probably not worthwhile. I also can't hear anything so i can't do any audio work at all.
That being said, if you're there in the same room and just want to use the tablet as a remote keyboard/touch surface, it probably wouldn't be completely awful.
"I also can't hear anything so i can't do any audio work at all." Good point. I do a lot of editing on my laptop and I was thinking of replacing it with a desktop and a remote tablet. Sit on the patio and have the benefit of the desktop's power. Doesn't sound like it is a practical idea. Thanks for your comments.
The thing that does work is to warehouse your media assets on a network drive and edit in Vegas on another machine. Not fast, but it works. Beware, most NAS routers are really slow, so my storage drives are on another wired computer.
If the tablet has remote desktop capabilities, to control the workstation, yes, I've done it on my audio recording workstation using Windows Remote Desktop. As far as real time video playback of the preview screen I don't think it would work too well depending on how fast WIFI network is now days.
I've heard that UltraVNC has pretty good video quality and audio.
He're a proof of concept video I made a long time ago, in my Sony Studio days, for someone asking if this worked for Cubase 4 of windows remote desktop control using wireless G to my audio workstation.
Several times I've thrown everything on an itty-bitty USB drive and have taken it and my laptop up to my "mancave" in Friday Harbor, an old sailboat I once lived on (back when I was thin, single, and broke). V9 runs great on a little Dell laptop.
Never thought of doing a remote edit, I guess because I'd assumed the screen refresh would be too slow. Didn't realize audio could come across too.
I've checked on renders and started a new one when the first one had finished from my iPad while out to lunch at a restaurant with wifi. Not exactly what you're asking, but quite useful none-the-less.
