Installing on several computers is not a problem but if you are rendering in poser on your laptop and at the same time using poser on your pc to set up another image. Then technically you (you being anyone in general that is doing this) are violating the EULA. I think someone mentioned they were running their laptop via remote etc and I think they mentioned that they contacted CL and they said no problem. I would suggest that if you do then you make sure you have written confirmation first (otherwise how do you prove it?) A company I worked for was hit with a very large bill for their missuse of software (not poser). You have to prove that you are not using the same software or that there is no posibility of you using the software at the same time. I take a laptop to work with me I could load poser on it and work in my breaks. I have it installed on my pc at home and work on it in my spare time. There is still the possibility that I could use both machines at the same time when I am at home. There is no proof that you did or did not use the software on both machines at the same time and that is were it gets tricky.
