Redundant splitfiles are your friend. Instead of inserting, say, 65
chunks 10 MB each the software inserts 98 10-MB-chunks with the
property that posession of *any* set of 65 chunks out of these can be
used to reconstruct the original file.

Resuming downloads works more or less automatically this way. Every
chunk successfully downloaded by one's node will stay in the store --
if 60 chunks were done before your connection goes down, there are
only 5 more to go. The exception is when the chunks got pushed out of
the store either by other chunks (if the store is not big enough to
hold them all) or by other data (if the user discovers that freenet is
not just useful to download your software).
