Sounds great -- the ai-chooser thing was always a kludge to
get round that weakness in the way the menu works.  My initial attempts
at delaying the choosers failed precisely because I was guessing wrongly
that isinstallable would get multiple tries.

Not sure if this makes any odds, but I was envisaging that all URLs
including file:/// might be usable, so that the differentiation between
network and non-network preseeding might be something that we could drop
at some point.  Also, we need the relative url stuff to be done regardless
of whether the initial preseed file came via http or from /hd-media as
that allows one to copy a bundle of preseed files from a web site onto
a USB stick and still have them work.  Just thought I'd mention that
as background of how I use this stuff, not because I think there's
anything wrong with what you've done (I'll tell you if I manage to find
anything :-)

Sounds like a good plan to me.  I'll have a play with it and see if I
can come up with anything I don't like.
