For any one interested in modeling for Second Life, we've just posted a new tutorial on creating sculpted prims via polygon modeling in Maya.
The tutorial can be found here: http://www-scf.usc.edu/~slsdg/mayatutorial.html (http://www-scf.usc.edu/%7Eslsdg/mayatutorial.html)
We're hoping that this tutorial will help make building in Second Life more accessible to a wider variety users. If you have any feedback, suggestions, ideas, etc. that you think will help improve the tutorial, please let us know at email@example.com.
