Do we have to embed a font even though the it is installed on the client side?

programming flash

I mean, if I want to make a textfield with some “Tahoma” or very pop fonts(that there’s surely on in the client), can’t I just leave a name in my ActionScript code? Just like the static-textfield in Flash CS3

for some reasons, I am using MXMLC.

any tips or conclusion? Thanks.
