You can substitute replication in place of dataguard if you want to show an active-active configuration. Replication however is relatively
complex to implement and maintain .. and thus there is a logical point that there is more chance of a replication cofiguration to have problems
which can ruin the maximum availability that the client was going for.

Oracle's 10g High Availability document does include replication/streams
in the HA technology.

However, RAC + Dataguard would be relatively simpler and more reliable as a MAA architecture than a RAC + Streams/MM configuration. The two configurations are however different in that one is an active-passive configuration and the other one can be an active-active configuration.

... my 2 cents.
