There's a consistency within Shaolin Luohan forms that is unique. They almost always emphasis some movements involving bowing the hands or a similar 'luohan' like gesture. For this reason, I wouldn't go as far as to say 'it is just a way of saying "Shaolin Quan".' It's a specific subset of Shaolinquan. However, I understand Sal's intention behind this comment and agree with it in general principle.
There's an interesting Luohan DVD in our Grandmasters series (which is mostly Emei-based masters):
Grandmaster Peng Gaoji: Arhat Fist
luohanquan 罗汉拳
In the final years of the Qing Dynasty, Yang Zhaoyuan of Leshan Mountain followed his master Shi Zhipu to Songshan Shaolin Temple in Henan Province to study martial arts. Yang mastered the Shaolin method and returned to Leshan to teach Arhat Fist in the Neijiang district. An Arhat, or luohan in Chinese, is an enlightened being of Buddhist mythology often imbued with magical powers.
I also did a series outlining the entire Songshan Shaolin Xiao Luohan form by Shi Guolin.
