"Live" queries in sql 2005 ?

A colleague was telling me the other day that in Sql Server 2005 there is a
special type of query you can do, whereby it runs in the background and
brings back results automatically, whenever they change. He referred to it
as something called a "live" query, but I'm not sure that's correct
terminology.
In theory you could run such a query, and sit back and watch the results
change in Query Analyser (or wherever). For example if you were monitoring
total sales, you could literally run the query and it would "auto update" in
front of your eyes, as sales increased.
Then you could theoretically write a client application with, say, a grid
which was bound to the "live query" and updated itself magically.
One could write a client app which polled the database every 2 seconds or
whatever, but that's not as efficient as picking up data *only* when it
changes.
Obviously it depends on the client limitations, but has anyone heard of such
a thing in SQL 2005?
Thanks,
