asset tag helper

Is it possible to add another asset tag helper
(ActionView::Helpers::AssetTagHelper ) ??
coz i'm using the ActionController::Base.asset_host = "http://
assets.example.com" for my static files.. and I want my app to get
video/flash files from that host too.. but the thing is only images,
javascripts and stylesheets have the asset tag helpers with them..what
if i wanted videos? any idea guys on how to add somethin like flash
url tag helper??

thanks =)
