I gave a presentation to the Santa Clara Valley chapter of the PSES in JUN2007 that has guidance on this topic. Find it at:

LPS is not sufficient, since the PoE conductors are of similar size and use significantly similarly constructed modular plugs and jacks. The maximum current that can be dumped into the network is 1.3 A. UL also has published some Practical Application Guidelines on the topic.
