One problem is obvious. Suppose the interior of a stasis field has
time passage at 10^-9 the ambient rate (31 years inside is one second
outside). Both regions have a local 100 W bulb lighting them.
Somebody is going to get fried unless the interface is utterly opaque
to all EM radiation.

Em is no problem in theory. Gravity is. As Einstein himself pointed
out, the big difference between EM and GR waves is that you can put
the former in a box (or equivalently keep them out).

However he is right about the quantum Zeno effect, if we'd build a
meassurement apparatus which had the momentus state of the system we
want to keep as an eigenvector and meassured often enough this would
in principle also prevent the system from interacting with photons or
gravitons (should they exist).

Of course thats a ridiculously impossible concept for an arbitrary
number of reasons, and might even be conceptually impossible if deep
entanglement between the system and the world exists, which is, for
macroscopic systems, probably inevietable.

[1 sec inside is 31 yrs outside but...]
Not necessarily.
The quantum transitions leading to light emission within the statis field would
also be muted. However, as you point out, there will be problems with external
interactions. IMO excluding them is part of the technical problem in order to
maintain the area.

A dynamical system which passes through a succession of states,
at constant time intervals, is a clock. Clocks measure times,
and, coupled with other systems,can also measure the duration
of a physical process. Clocks can also be used to control the
duration of a process, or the evolution of a physical system.
In this case if a clock has a good time resolution, there is
some energy exchange between the clock and the controlled process,
that is the evolution of the physical system under control.
Both the evolution of the physical system and the clock
are then perturbed, because when you include the clock mechanism
in the Hamiltonian describing the quantum system to be observed,
or to be controlled, you get this perturbation. If then a clock
is too precise, a sort of quantum Zeno effect occurs - the evolution
of the physical system under control may be even *halted*.

[I do not know if the above was taken from a paper, i.e.
a paper by Asher Peres. In this case you can find the paper
here http://kh.bu.edu/qcl/ ]
