...as chvt(1). I'll just run an extra X-server without WM on a separate virtual terminal and switch to it remotely via SSH. It won't give of fancy transition animations à la Beryl or Mac OS X, missing some of the futuristic-look-factor, but the functionality is what counts, right?
On a side note, this whole plug-me-in-and-I'll-autojoin-the-larger-setup business reminds me of reading about "FlashMob computing" the other day. It sounded pretty much like they were still missing such "auto-integrate" (and auto-"exegrate") functionality...
PS. I apologize for a lack of links in my posts, but I've been sending them from my cell phone (yay advopost) and can't look up the references, so bear with me for having to google out the links yourselves... ;)
