[Opensim-users] Mesh noob question

[Seren Seraph]

My most basic question is what can and cannot be done with mesh in
opensim and/or SL?  Can I for instance take a mesh model of a spaceship
and sit inside it and fly it in opensim?  Can I build mesh exotic
buildings and use them in all the ways I can not mesh builds?  I
recognize I can't do various prim manipulations on meshes in world but
don't have a good feel for what limitations this imposes.  Can I create
linksets that include mesh and non-mesh items and add scripts and so on?   

Is there a good FAQ or paper on this somewhere?
