Yes, the presentation level is mostly in nautilus.

Under the hood, applications can declare themselves as capable of
handling autorun for one or more kind of pluggable media by adding
"x-content/foo" to the "MimeType" key of their desktop file (e.g. a
music player might specify "x-content/audio-cdda" if it handles hotplug
of audio discs); GIO uses the XDG machinery [1] to guess the content
type of the plugged media, and nautilus gathers this information to
build the choice offered in the autorun dialog. The code for this is
mostly in libnautilus-private/nautilus-autorun.[ch].

Note that nautilus itself has a binary (src/nautilus-autorun-software.c)
that register itself for the "x-content/software" type, which is
launched if the plugged media contains executable software.


Hope this helps,
