Notes

Opera Mini ignores the blur-radius set, so no blur effect is visible. Text-shadow behavior can be somewhat emulated in older IE versions using the non-standard "dropshadow" or "glow" filters.

IE 10+ supports a fourth length value for the shadow's "spread". This is not (yet) part of the specification.
Partial support in Safari 3.* refers to not supporting multiple shadows.

Bugs

According to http://code.google.com/p/android/issues/detail?id=7531, text-shadow doesn't work on Android (at least 2.3, from testing) when the blur-radius is 0.
IE10 doesn't seem to render rgba(255,255,255,0.25) properly. It seems to ignore the alpha value and uses 100% white instead.
Safari 5.1 requires a color to be defined for the shadow.
