I don't believe that notecards are automatically delivered when a prim description is sent, it would have to be requested just like any other asset would be. Using a notecard may require multiple steps to retrieve the entire text of the .obj file, but the viewer must be capable of asking for the text of a notecard and receiving it already, or it would not be able to display them at all. There may be other alternatives. Upon entering a region, a special viewer could announce some message on some high numbered chat channel, and a script in a prim could respond with a specially formatted ownersay message that says something like: "*special message* if you're capable, please download a mesh description from http://mymeshstore.com/uuid.obj and display it instead of this prim". Normal viewers would not be likely to see the message as they would not normally be sending instructions out on that chat channel, and the viewer that could use the message could parse it, see that it was a special message, and download and display the mesh rather than showing the user the message.
I still think the notecard can work. OBJ files are ascii text so should be compatible with a notecard as long as it can all fit. OBJ files can describe many different geometries quite effectively, and the size of the files can be minimized by being prudent about not using excessive precision in the floating point numbers contained in the file. If there were some geometry specified in the file that the viewer could not render, then it could be ignored, an error could be displayed, or some other geometry could be displayed in it's place.
