Re: behind the slide technique... SLO100/Bogner/Eternity
Yeah, I could share a few.
The right hand muting part of it is as important as what you do with the left hand slide technique. Get used to muting the strings you aren't using.
Open tunings are pretty easy to get started with. Open E, D, G and A are the most common. Standard tuning of course makes it so you don't have to go get another guitar during the show. Also, for me, open tuning is like having to re-boot my brain to think in a different language. I know the fretboard in std. tuning. You could spend more time and figure it out with open tunings. That's what Derek Trucks did. Everything's in open E all the time. So, he can do slide, single note leads, chords and everything else in that format.
Learn some of the simple, cliche type licks. Practice those, and then sort of daisy chain them together to expand your vacabulary.
Most people will tell you to keep the slide parallel to the frets at all times. That's good technique, and should be observed early on. However, my basic approach is to first learn all the conventions, then break all the rules. Tilting the slide is cool for certain things, but that comes later.
For the most part, keep the slide directly over the fret for proper intonation. Again, I bend the rules, and like the microtone "out-ish" feel for certain things, like a flat 5th.
Listen to the guys that do it. There's a pretty long list but I'd include
Muddy Waters
Elmore James
Duane Allman
Bonnie Raitt
Warren Haynes
Derek Trucks
Sonny Landreth (I've read that he uses BTS technique, mostly with chords)
Lowell George
George Harrison
Take your time. Don't rush the notes. Bonnie Raitt is good at simple lines that just sing and evoke a special charm.
Here's a good website or two:

In these demo's, I demonstrate "behind the slide" technique. That means I keep the slide flat across the strings, and sound notes with my first 2 fingers behind the slide to create some phrases that would otherwise be unavailable before. I can also use my pinky to hit notes ahead of the slide as well (I wear the slide on my ring finger).
