same metapsionic feat applied to a power multiple times?

[JuzamDjinn]

The no-nonsense guide to psions states, "unlike metamagic feats, you can apply the same metapsionic feat to a power more than once. You may have to show your DM the section of the XPH/SRD on applying metapsionic feats to powers."  I looked in the XPH and could not find this rule.  I also tried a search and couldn't find a discussion of this topic. 

Where exactly in the XPH does it say that you can apply the same metapsionic feat to a power more than once?  I can't find anything to "show to my DM" in support of this rule.

It's in the lack of something stating you can't. The requirements for adding it is expending focus and spending the extra power points, and unlike metamagic, there's no general rule that disallows using the same one.
General rules for metamagic feats
General rules for metapsionic feats - note the lack of a 'multiple metapsionic feats on a power' section.

Thing is, you'd need a way to be able to do this anyway.
Such as: a way to not need to expend your focus; the ability to get more than one effect per focus expended; the ability to have multiple focuses.

Wouldn't this go under the general rule of multiple things from the same source not stacking?

2 Linkeds at once = yummy.

iirc, the stacking rules only apply when a bonus is applied. any other effect is not technically covered by the stacking rules. i could be misremembering.
