Yes, absolutely. For example, we have many folks using our Windows and Unix apps and technical add-ons on our univeral forwarders, which are primarily scripted inputs.
Yes, the configuration is identical to the one on the indexer. The main thing is that the forwarder must be configured to send the data somewhere, as it does no indexing itself. You can download the Unix TA at http://splunk-base.splunk.com/apps/33800/splunk-for-unix-and-linux-technology-add-on and look in default/inputs.conf for an example.
