ne vs -ru with certain motion verbs

[Tirea Aean]

We already know from Frommer that we are to use ne with za'u and kä, but what about pähem and others? Tì'efumì oeyä (imo) they all use ne instead of the -ru ending:

Oe pähem ne kelku
Not
Oe pähem kelkuru

Perhaps even ro+ could work with pähem?

Thoughts on this?

[Plumps]

Mllte ngahu ... no -ru with these

Maybe it's too idiomatic but at least with pähem with have this example from here

Fìtseori ke tsun kawtu pivähem tìyo'ne; tsranten tìpähemä tìfmi nì'aw.
"In this art it's impossible to arrive at perfection; the only thing that matters is the attempt to arrive there."

Plus the behind the scenes transcript and the movie has

Pìyähem fìtseng ye'rìn.
"(The Skypeople) will soon arrive here."

Which leads me to believe that it behaves similar to za'u

[Kemaweyan]

Mllte. I think it's quite obvious

This comes from a post I made http://forum.learnnavi.org/learnnavi-community-support-board/keeping-the-feeling-alive-heres-how/msg551188/#msg551188, where I wrote

*Oe pähem nìzawnong kelkuru!

It kind of felt like an adposition would work here, but I wasn't quite sure it was right. Now, I know why it felt like an adposition would work. (now, to remember this stuff...)
