Well on some BD-J discs it works - if it the BD-J code has been written to do it.

It's not just 'resume' that BD-J causes problems with, but other playback controls (eg. trick play functions) that BD-J causes problems with, depending on the player. Not just BD-J either but any Blu-ray title according to page 17 of the BD60/80 manual, eg. on BD-V slow motion only works in forwards (I guess on DVD it works backwards too), on BD-V frame advance only works forward (I guess on DVD it works backwards too), etc. Even Frame Advance doesn't work on some BD-J titles with the BD80.
Basically Blu-ray (and BD-J) should give you more functionality than DVD and not less. Features that worked on DVD should work on Blu-ray (BD-J is supposed to be about 'enhanced interactivity' yet some of the interactive features of DVD and also some non-BD-J Blu-ray titles, don't work on BD-J Blu-ray releases, also loading times are a lot longer for BD-J too.
This is the Resume function of the Pioneer DV-600AV DVD player which can remember the playback position of 5 DVDs - unlike with Blu-ray BD-J titles, most of which aren't able to remember the playback position of 1:
Resume and Last Memory
With the exception of DVD-Audio and SACD
discs, when you stop playback of a DVD, CD, or
Video CD/Super VCD or DivX video/WMV
is shown in the display
indicating that you can resume playback again
from that point.
If the disc tray is not opened, the next time you
start playback the display shows
and playback resumes from the resume point. (If
you want to clear the resume point, press
With DVDs and Video CD/Super VCDs, if you
take the disc out of the player after stopping
playback, the last play position is stored in
memory. If the next disc you load is the same
one, the display shows
and playback will resume. For DVD-Video discs,
the player stores the play position of the last
five discs. When one of these discs is next
loaded, you can resume playback.
