It needs to be able to name a platform, media type, IDE, all at once. E.g., "I'm going to use Flash", "It's a Flash game", "Hold on, let me animate it in Flash". The name should be able to go in domain names; e.g., "superfunflashgames.com".

Basically, it has to have a name amiable to becoming an umbrella term. That gave Flash such a "universal" connotation.

I hope this makes sense - trying to convey the _peculiarities_ of "Flash" which made it (as I see it) successfull and distinct in character.
