AD&D1 rules: I don't allow Blink, Teleport, Dimension Door, or TP w/o
Error through a P. Sphere (or Wall of Force).  I do allow
plane-shifting spells like Plane Shift, Astral Spell, and the
equivalent psionic disciplines, since they don't go "through" the
sphere.

kjenks@gothamcity.jsc.nasa.gov counters:
Yes, the spell caster can move in/out at will, but he can't see 
through the sphere (it's opaque to everyone) and nobody can cast
spells through it (even if they make their MR).

kjenks@gothamcity.jsc.nasa.gov counters:
No, just like above.

kjenks@gothamcity.jsc.nasa.gov counters:
Just once.  It's only one spell.

kjenks@gothamcity.jsc.nasa.gov counters:
It filters out all gasses except O2 going in and an equal volume of
CO2 going out.  These can pass through at a "gentle breeze" (no
hurricanes).
