apparently with Daz Studio you can export bvh file for use in Second Life and Hexagon 2.5 has the SL primitives.

That's not an exclusive Daz Studio problem. SL can import any BVH file.  The primatives are a special kind of TGA file. There is no way you could ever export any usefull model from Poser/DS into SL using this method.

Linden Labs are very lax about copyright infringement, and they have always been that way. It's the number one complaint from SL community and it comes up over and over on their forums. It's an unfortunate fact of life that a few 100 users, out of millions, can cause so much grief. Pretty much the same that I have heard of Poser users who post copyright material on Taiwan or Russian website.

The TC2 converter will probably dissapear when Daz gets enough heat put on them. But don't expect to get any response from LL. They are quite happy to sit back and turn a blind eye as long as they are making money.

Just a thought on quality. Even with the TC2 program I don't think the textures simply converted from Poser could be as good as the ones made by the top designers in SL because of the way the lighting is handled.  The limited lighting in SL means that the best textures have a lot of shading 'baked' in. A flatter texture designed for Poser to do the lighting will look kinda flat. I have tried making textures for both and found that creating a texture that looks reasonable in Poser is far easier than creating one that looks good in SL. (I use the term 'good' very loosly here given my limited PS skills).
