Install Philologic 4?

One of the best search engine for XML/TEI documents is Philologic (ARTFL). Its installation needs administrator privileges, so it has to be something done on the server side.
I do not know if there are other Digital Humanities project on Recaim Hosting using TEI, but it if it is the case, then maybe it would be great to have it as an option. Not sure about the licensing question, though.
