Thanks for the pointer! I hadn't considered the problem of actually
verifying that the data returned was correct. I'll keep that in mind!
In my basic hand testing I do actually do MD5 sums to compare the
original and downloaded files. In a server test this could be done the
same way - although probably not on every file for a load test.

Hmm... perhaps I should add a check for sendfile() in oftpd and use that
when, well, sending a file....
