[Grids have long been associated with "sharing" of resources particularly
high performance computing facilities, but their real power may not be so
much in sharing, but empowering users to give them remote access to
instrumentation and other facilities. The following paper by Laura Pearlman,
Carl Kesselman, et al is a good example of this approach of using Grid
technology to allow researchers access to a distributed set of seismology
equipment and linking them with computational simulation processes.  Another
good example is the upcoming EU eInfrastructure project GridCC which will
provide real time control for remote instrumentation and the National
Research Council SpectroGrid which allows users to monitor and manage date
form a remote NMR farm http://www.gridtoday.com/04/0223/102708.html

Abstract
Earthquake engineers have traditionally
investigated the behavior of structures with either
computational simulations or physical experiments.
Recently, a new hybrid approach has been proposed
that allows tests to be decomposed into independent
substructures that can be located at different test
facilities, tested separately, and integrated via a
computational simulation. We describe a Grid-based
architecture for performing such novel distributed
hybrid computational/physical experiments. We
discuss the requirements that underlie this extremely
challenging application of Grid technologies,
describe our architecture and implementation, and
discuss our experiences with the application of this
architecture within an unprecedented earthquake
engineering test that coupled large-scale physical
experiments in Illinois and Colorado with a
computational simulation. Our results point to the
remarkable impacts that Grid technologies can have
on the practice of engineering, and also contribute to
our understanding of how to build and deploy
effective Grid applications.
