real time reporting + OLTP dbs

How does one implement real time reporting off of data from the OLTP
systems. Right now we run nightly extracts and load into OLAP DBs to
minimise locking,etc while the extracts are being run. However our customers
now want to see real time data as soon as possible and we cannot give them
access to the live OLTP systems. Are there any ways to implement this
efficiently ?Have you tried replication? It should give you more frequent updates.
You might want to consider using read uncommitted query because replication
also needs to make changes to your OLAP database to keep data up to date.

OLTP dbs to serve the reporting needs besides the administration needed to
support it ,etc..
