async texture apply (WebPlayer)

unity3d support native texture id and pointer to direct3dTexture and it’s good for standalone applications. but for webplayer we can’t use it for security reasons.
if necessary in web applications are often compress DXT or texture.apply we get delay in main thread.
is it possible to use a similar function (texture.ApplyAsync , texture.CompressAsync) to avoid prolonged execution time in the main thread (for webplayer) ?.

The devs at Unity keep an eye on feedback.unity3d.com. See if your idea is recorded there, and if not, add it.
