Cool - I think this feature is available directly with the service that is downloadable from the F-Script homepage:
"The F-Script Anywhere injection service, developed by Silvio H. Ferreira, lets you easily inject a whole F-Script environment in any running Cocoa application, providing F-Script Anywhere-like functionality…"
Just to clarify F-Script is suitable only for debugging Mac apps. Super Debugger looks really cool for iOS.
Also, F-Script doesn't leverage lldb. The use of lldb in the example here was just that you can use lldb to attach to and load a library (bundle) into an arbitrary app process.

F-Script is pretty amazing, and was a great tool for helping me to learn Cocoa in particular.
