I am not sure what the ultimate scale software should look like but I bet it would look a lot like the new soft indicator software from Progressive Scale and Software Solutions. This software has it all. Multiple scales, up to 8 I think and real flexible bar code label printing and simple database integration. They have a downloadable demo and it gives you 60 try's before it goes out. It could use a little more documentation, but it all seemed to come together once I down and actually read the help files. http://www.scaleprogrammers.com/soft_indicator.htm.
And if you like winwedge, you'll LOVE this one.
