SecondLife uses special low rez figures and all other meshes are limited to what is availible in second life (basically just primitive shapes) so there is no way to actually import any poser items to second life. There is a new sculpt primitive that allows a map based on a low rez mesh to be produced in some modelers which can recreate that mesh in SL the mesh size is only 1024 vertexes though. there are some poser artists who are also doing textures and other items in SL, though as I said that is a totally seperate venture, and you are not likely to find stuff from Poser in SL. one thing that can be done in poser for SL is bvh files using the special poserized SL figures, these bvh files are used to animate figures in SL.
