Blocks currently has a dumb ~250Mb limit on file sizes. This is
because it only allows a single 64Kb header block, which only
has space for 4087 data block IDs. Each 64K data block is actually
contains 65392 bytes of data, so the largest file you can upload
is 4087*65392 => 267257104 bytes => ~254Mb. Perhaps this should
be on the web page somewhere?

Once we've sorted out the network building and file advertisement
logic in Blocks I intend to look at this problem, especially
since Blocks would appear to be much more suitable for very
large files than some of its competitors (if it really has any :)

One possible solution is to allow the chaining of header blocks,
so that the file can be any size upto ~2Gb, but files > 1Gb run
the risk of trashing all the caches they pass through due to
their enormous size, so perhaps the caching logic would have to
be upgraded as well? Its definately a problem for later on though.

Cool, its a pity FLTK doesnt have double-click events in
FLTK Browser widgets, but other than that Im pretty happy with
it so far :)
