Sometimes, you really just want a RT front panel. Of course, there is no real front panel, but when you run in interactive mode Labview is automatically setting up network communication to pull data from the RT target and push data to the RT target. Wouldn't it be great if you could just convert that whole front panel into a basic host VI? Right now, you have to manually convert all controls and indicators to shared variables. Granted, this does force you to be very careful about limiting the number of network-shared items that you have, but sometimes you really just want to run the VI in interactive mode...but deployed.
Or, better than that, convert everything into a web service and automatically build a silverlight UI (using Web UI Builder) which is hosted on the cRIO. Anything that provides you with a quick and easy way to convert from the rt debugging UI to a basic host VI would be great.
