We're in the early stages of the new Composite WPF. We've received a bunch of feedback from customers that the name needs work and doesn't roll off the tongue. This applies to the short form CWPF or the longer Composite Windows Presentation Foundation. We've been playing the name game internally to see if we could come up with something more simplified that does not contain WPF in the name. Here a list of some of the ideas we've been throwing around. We're trying to avoid something that we would have to get trademarked.
PRISM - something like PResentation Integration SysteM.
cx - Composite eXperience
cx - Composite eXtensions
cui - Composite UI
mui - Modular UI
glui - Glued UI
What works for you? Do you have any better suggestions?
