This is a nice spamfic. You didn't really write this in a hour, 
did you? :)
Only questions I have:

        Ryouga 1 walked down the street, once again in his own time.  He could
only hope that his counterpart would fade away once he returned to the
future so there wouldn't be a paradox or something like that.  He walked
up to the door of the Tendo Doujou, a week and 3 days later that he had
planned, but he was getting better at it, and knocked.

[snip]

        "Oh, by the way, Ryouga.  You wouldn't believe what happened
yesterday!  Apperantly, Dad and this other guy made this arrangement
where one of us, including my sisters, is going to be arranged to marry
this guy's son....

Question 1: If Ranma didn't show up until now, how did Ryouga meet
Akane?
Due to Ryouga 1, young Ranma and young Ryoga fought their duel, so what
caused yRyouga to meet Akane, since he wouldn't be following Ranma
around
anymore? Akane could say something like "you only wandered into Nerima
a few months ago" and give a reason for the young Ryoga who fought the
duel with Ranma to meet up with Akane. Since Ryouga1 said he was in his
own time, which would have been a while after the duel & Ranma's arrival
in the original timeline, wouldn't that mean that Ranma stayed in China
a lot longer? Maybe young Ryoga won the duel, and as a result Genma
made Ranma train *real* hard in China (perhaps with Shampoo or Cologne?)
Does anyone actually understand what I'm saying, or am I
raving again?

Question 2: What's going to happen with Ryoga2, the one who originally
was going to beat Ranma to a bloody pulp before Ryouga1 stopped him? 
Doesn't he have a Nan-Ban mirror as well, meaning there's two Ryougas
running around messing with time/space? Just fading out of existence 
seems too easy and contradictory to the way the Nan-Ban's worked so far.
Possible answer: He returned and then traveled again, becoming Ryouga1.

Question 3: Does Ryouga1 who's boyfriend to Akane still have the curse?
Since he's supposed to be the older version of the young Ryoga who
fought Ranma in the duel, he wouldn't have any reason to follow Ranma
to China and get dunked in Jusenko, so wouldn't his curse disappear?
On the other hand, maybe Ranma won and Ryouga followed still him.

I know this was just a short exercise, but I think it has a lot of 
potential for something longer, so I asked these annoying questions.
 Please continue it!
