McLeod's Imaging over here.
Despite being a TMW customer yourself I'd consider giving McLeod's Imaging a look. It does have the ability to integrate with what you have mentioned and more.
I've even heard of folks buying their imaging solution a la carte without LoadMaster since it was so powerful.
Talk to Mike Ayersman and tell him I sent you. 509-448-4798 or Mike.Ayersman@mcleodsoftware.com
If you can try and make it to the next Imaging Conference they host from time to time. It's a great way to see the product in action and meet existing users.
