of course it will work.  it just won't be particularly fast.  specifically,
it won't allow tcp to discover the actual end-to-end bandwidth*delay product,
and therefore tcp won't set its window size advantageously, and some or all
of the links along the path won't run at capacity.  packet reordering is not
fatal to the technology, but it is fatal to the business.  "not everything
that can be done, should be done."
