I started a quick attempt at implementing download resuming ~8 months ago, shortly after posting this bug, however I had seen news that Wubi was being discontinued so I stopped working on it.
It looks like Wubi lives on (maybe it's just not being put on the release DVDs ?) - so I've linked my current work as a related branch lp:~ajperry/wubi/resume . This is incomplete (still needs some additional UI), but it seems to work and will resume from a stopped download.
