cross database dependencies

As far as I know SQL Server 2005 lists only dependencies within the same database. In many cases though there are objects in one database depending on objects in a different database on the same server. I unsuccessfully looked for a tool to list those and I ended up creating a script to do the job instead. Any improvements are appreciated, e.g. the script uses syscomments which may no longer be available in the next SQL Server version - I have not found a replacement sys.XXX table yet. Please note that you need to use a connection with access to all the SQL databases on a server and that it may take a while to run the script below if you have many databases with numerous objects in there. On the other hand these are exactly the cases when you need to know which of the thousands of objects are dependent on the table or view you are looking at.

P.S. Does anybody know where the extended properties get stored (hint - not in syscomments)? I was looking for those too, since often I document in the description of a field that it links to "DatabaseABC.dbo.TableXYZ.Field1"

for extended properties, see fn_listextendedproperty and sys.extended_properties
