By strict RAW teleportation should count as having moved x distance, some DMs may balk at it. Myself? Scout's weak and I like the mental image of short hop teleporting around catching foes offguard for skirmish damage, so I'm fine with it.
Oh, I agree by RAW it works. But as you implied it's in how one views skirmish. We tend to view the skirmisher as the juke and jive combatant whose moves are so chaotic and quick that it gives him an extra oomph. Plus the 'force' of the movement gives him more. Our current DM hates the idea that I can skirmish when flying (via the Animal Devotion feat) but is resigned to it.
I'm not entirely convinced that it's necessary to have multiple Ranger levels because with Swift Hunter it's all about the skirmish. Otherwise, unless you're being silly like me, I wouldn't advise adding single levels.
In my case, though, I walked into a well-established world (from 2e) with the full understanding I probably wouldn't be playing it that long. In fact, after the next session I may never see the character again (we have 4 potential DMs). So when I created my character I did so by thinking what advantage I would gain in the short term. As such, I added Monk 1, completely forgetting I could never level up in Monk again. This meant I could only max to level 2 in other base classes. Then it turned out we were going to be playing these characters longer than originally mentioned.
So I decided to take my error and run by adding Fighter and Ranger. I may add another Fighter (for the feat) and probably Ranger 2 (allowing me to retrain 2WF). Cleric I've already mentioned and probably a Rogue level (I forgot why though).
So I'm pretty sure if we continued I would wind up as
Scout x/Monk 1/ Fighter 2/ Ranger 2/ Cleric 1/ Rogue 1
and just for S&G's Barbarian and Bard.
Of course, if I started straight off at level 1, things would've been different.
Two reasons.
1) I've gained two (three?) levels and haven't made a dime. Even though I'm basically part of a criminal organization that is constantly making money. (One of the reasons I'm moving to take control of it.)
2) I've pretty much determined that if something isn't your basic plus- weapon, or magic item (like bracers), then finding them to purchase is unlikely. Even though the DM uses MIC (for items we find and other characters in the world have found). Yet, when I added a second character (the DM wanted to merge two groups) I was able to buy anything I wanted when rolling it up.
I'm already better* than anyone in the original party and I think the DM is reluctant to allow me to get even better.
*The DM wanted me to play a were-rat so I did. I rolled really well (16, 4x15, 11) so I have the second highest number of hp, DR 10, and an AC when skirmishing 10 pts better than anyone else. My saves are roughly 4 or more better than anyone else. And I have the least magic items: low versions of a single magical melee weapon, ranged weapon, bracers, and a ring of protection. Oh, and I snuck in gloves of Dex +4. In my "are you any good" trial I literally beat the crap out of their big fighter and took a grand total of 14 pts. of damage (mostly from a single crit).
