> Could be useful.  You'd have to use caution in what URLs you reference, since it's pretty much executing arbitrary code.  And, unless you were always on a trusted network including trusted DNS, you'd want to use HTTPS and a trusted CA list.  At that point, it becomes less lightweight.

True, the whole security concern complicates matters. But in the simple cases I have (teaching purposes, URL local to the CS dept, etc.) that's no more worrying than posting a rkt file on a forum and ask students to download it and require it. But that would be simpler, and would allow for posting updates "transparently".
