I was thinking about this kind of utility the other day.
With the latest avalanche of major and minor versions there are some nice features but you ‘re sure to get them only if you have the latest player.
So how about telling the user more about his flash player capabilities. Like if the one he/she has supports bitmap data, or HD video or the new sound features.

Should have known Aral would beat me to the punch on something like this! It is good not to have too many technical details on a client-facing version, though, so not all is lost!
