Subject: How to get a list of all available PVs

Hi,

Sorry for this newbie question... I come from the Tango community, and I am 
quite lost with Epics

I am a developer of Taurus [1], a GUI library initially designed to provide 
PyQT GUIs on top of Tango. But our goal is to also support other 
communication/control systems such as Epics.

I recently implemented some very basic support for epics in Taurus (just a 
proof of concept) using PyEpics, and one of the first questions that I came 
across is:

How can I obtain a list of all PVs that are available?

... or even better, can I get a list of all PVs whose name contains a certain 
prefix?

The reason I want this is that I want to create a browser/selector of PVs. I 
do not care that much if the method is slow (I could live with doing it once 
and only manually refreshing the list). 
But I need the method to be generic, i.e. it should not assume some non-
standard service (such a site-dependent database) to be available.

Is this possible at all?

Cheers,
