I somehow doubt the latter part. Yes, That jutsu is more or less the fastest thing possible (since you can't go faster than light), but by taking a shortcut, like you said, Minato essentially traveled to all distances in the same moment of time, no matter how far. Even with traps, she would need to predict Minato's every move to set up perfect traps. See the thing is, he's not a robot that's totally predictable and he could obviously manipulate time and space so he could obviously freeze time for himself as well. Even IF she set up traps and predicted his every move(impossible, btw), she would not be able to surprise him OR catch up with him, because she still travels at a finite speed, while Minato could essentially travel the width of the universe in the time taken to use the hirashin.
Same goes for Tobi. She simply cannot beat him. Even on paper.
Yeah. The distance matters little since, you would get there instantly regardless of the distance. Even light has to take time to reach a certain area exactly, even if that time is only a fraction of a second. If the justu can't defeat Tobi's "portal" route of manipulation. It can never beat Minato's version.

"In most practical cases, light can be thought of as moving instantaneously, but for long distances and very sensitive measurements the finite speed of light has noticeable effects"
http://en.wikipedia..../Speed_of_lightNote: There is also a section talking about scientist possibly discovering something faster than light travel.
So let's look at this at a much greater scale
Let's say you want to travel 10 lightyears distance wise. Light moves at 671 million miles per hour. It will take you ten years going the speed of light to reach the distance of 10 lightyears.
If you were to use space-time manipulation, it would take you 5 minutes at most to travel the same distance (depending on how much energy it takes to compress the space). For light to go from the moon (bounced off) to the earth would take 1.255 seconds. Space-time manipulation: You would be on the moon even before the light started to move.
I think what is incorrect about it is that we use the term "travel" when it comes to the Hirashin because there is no "traveling." If you think of the term "traveling" as "An object moving across space" then this does no such a thing. The object technically doesn't move at all. Instead, what compresses is space itself. Movement only really occurs before and after. Not during.
Of course, there's a limit to the Hiraishin. The destination is limited between where the user is and where the seal is. Move the seal or prevent the user from dropping a seal, and there's no way the user can use Hiraishin. Just as the Summoning technique creates a seal instantly to create a destination, no seal means the user's not going anywhere.
That is its only weakness and it's hardly a weakness at all since he can put the "seal" on anything, anyone, anywhere. There are so many ways to get around this weakness that it hardly seems like a weakness at all.
But then again, both Tobi's and the Heavenly transfer need anchor points to work so it it is even ground on this one. Tobi's is is that he physically has make a portal using his eye which is why I think the Hirashin is faster simply for the fact that it doesn't need to use portals like that.
I think a bigger more obvious weakness is the Chakra reserve. Their energy is not finite and even Tobi can only use his move for 5 minutes at most in intervals. This is why not many can use Minato's because it requires a lot of it to do such a move. Naruto, with his massive chakra reserve, should be able to learn it no problem and use it as effectively as his father could.
