Is there any one template which works better than others with respect to mime attachments?

I'm having trouble with the brewt one in terms of "doing the right thing" of either displaying or downloading. Would it be possible to provide two links to either "view" (if possible, taking an educated guess based upon the type if we can do it inline) or "download" (just stream the type with the appropriate header to the browser?)

In particular, if you try to open a Powerpoint presentation, it doesn't seem to pass the data properly.

Thanks for any and all help and tips!
