IMO it is not enough to deter SBT (BST isn't a great idea since scry has a 1hr casting time and most of the buffs will wear off!)
Actually, my players use buff (including 1 rd/level spells), greater scrying, and then teleport. Greater scrying takes only one action. And you want to attack as soon as possible so the enemy has less time to react to the sensor (if they see it).
They don't care about the teleport table and missing teleports because they can teleport again next action. 3.5 makes this harder because you can't just teleport based on a description.
Part of the problem is that bad teleports are not that bad. Maybe 1d10 damage, but usually just end up 1d10 x 1d10 % of the way off and just teleport again. Several 5th level spells to get the job done, or now that Greater Teleport is on the table, they don't worry at all.
The main reasons why it won't deter it
a) wait until you can scry them while they are asleep or bathing so they don't have all their gear handy.
Good point, my players have never thought of this, yet. I added the audible sound to my solution to avoid teleporting in when someone is sleeping, or arriving invisible or in their closet or something. I didn't think about bathing or other comprimising situations.
b) the ambushers can take enough time to lade on as many buffs as they want, 1 or d4+1 rds isn't enough for the assaulted to buff themselves as much (even if they were aware - see (a))
If you arrived unable to act for 1d4+1 rds, they enemy could slaughter you before you got a chance to act. That would deter most SBT (or BST).
Your option (3) would work - if the people at the destination can shove some furniture into their arrival point so the teleporters automatically get an initial "Mishap" it means that the attackers would always want to arrive in an empty location, making the whole thing less of a duck shoot for them.
I like that. For that matter, you could go stand in the incoming spot and block teleport.
Hmm. More thought required. Thanks.
