I just wanted to note this, if you haven't seen it already. There is now a free app in the iOS App store, from Basis Design who is the developer for Barcoder on Windows Mobile, that integrates with Barcode Solution! I've downloaded and used it lightly and it seems to work pretty well. Check it out for yourself: http://www.barcodeessentials.com/
I am in no way affiliated with Basis and happened to stumble across it while searching for a solution for something else in Barcode.
Thanks!
Update: They've added a product road map page to their site which lists all of the great features that they're working on too. http://www.barcodeessentials.com/product-road-map/
