You can have poser 11 installed on more than one machine, however running more than one at a time is probably against the license restrictions (poser 2014 checked your local network and wouldn't let you run the program on two machines simultaneously). However poser 11 includes queue manager, which allows you to render over a local network without poser itself running on the other machine, so it is quite possible to render on one machine while working on another.. It also has a render in background option.
