Dear Dawid,
Here are some answers to your registry questions.

Yes, it is possible to have a single GRIA registry containing all GRIA
services in an organisation.
The registry service is a factory for registries. One of the registries
at the service could be used to contain all the organisation's services.
You might also want to use a registry to record all resources (both
internal and external) available to a particular project.

The services would have to be added by hand by someone (but this
information is not rapidly changing of course). It is easy to do in the
GRIA GUI, just using drag and drop.
Some information in the registry is dynamic. For instance, the registry
will pull usage information from the SLA service so that the usage of an
SLA can be queried as part of a service selection decision.
Unfortunately the state (up/down) of a service is not recorded.
Regards,
Stephen Phillips.
