if the portal is still open, space-time curve through it and all distances and other relative effects act as normal through the portal. now, this is physics based on wormholes, where things like gravity and time should mesh through the portal.
basically, if you are half way through the portal, your two halves aren't an incalculable distance from each other, so why would your summon. Your enchantments on you that have a distance of you, don't have a problem extending to your hand that is through the portal. etc, etc, etc.
That arguement does make sense when you have one individual with a portal. What I am asking about is the case of a summoner and their eidolon, which is two separate individual creatures. The moment one of them crosses a portal, they are both near each other, by your argument, but also on different planes at the same time.
In the case where they are merged there is no issue, but since a eidolon requires to be within a certain distance of their summoner, which distance would you use, as I am pretty sure every plane in existance is not ten thousand feet of each other
I'm saying if a magical effect can pass through a portal(such as on a person), so can the magical link sustaining your eidolon.
always use the shortest path for determining distance(almost always this is a straight line), and I don't believe you need line of sight or line of effect, so according to physics, the shortest path would be going through the portal.
basically, if there's an open portal then there is nothing blocking anything from happening between those two planes. At best you can argue that if you can't get line of effect through the portal it would sever the connection.
As long as there is line of affect that distance should count so the eidolon should be ok.

the thing is, and I know I'm being pedantic about this, is wormholes curve space, it doesn't make a tube, the edges curve so you couldn't cut your hand on the edge of a portal, it would bend into the other end.
like anything coming in parallel to the portal at it's edge would or at least should come out reflected on the other side like it got rotated 180 degrees.
basically, it's impossible to not have line of effect through a portal.
DIAGRAM:
I = portal
X = trajectory of a straight line through a portal.

_X__I__X_
so, some line between the sum and eidolon will always cause them to have line of effect(I hate the word affect, it's a trap) so long as the total of their distances from the portal does not exceed their total max distance allowed.
Ok, I'll stop now before I start thinking about space-time too much. T_T
Bandw2 we actually agree on how to play it in the game. If the portal is open I see it as having line of affect. Now if that portal closes then the eidolon would be banished.
