  I know,  I need to get some of those too.  One place I
recall using them was
 for an IBM external floppy drive enclosure -- though they used standard
 philips-head screws in some of the holes.  I got them out finally and
 threw 'em out.  :-)  It'd be nice to be able to deal with them easily though.
The 6-lobed Torx security bits are pretty easy to come by just about
anywhere.  The 5-lobed Torx security bits, on the other hand, are
considerably more difficult to find, though not unobtanium.
Torx in the non-security version is great.  I'm working on a
construction project on the house and much to my surprise, I found
that ceramic-coated deck screws are now made with T25 heads.  Much
better than the older square-drive or phillips types.
