I'm not an expert on this, but provided the functionality actually exists on 
the major platforms of interest, it seems sensible to me. We should check for 
the existence of this functionality on at least the major platforms of 
interest (is there a list of known ports?).

Please don't use "long long" - Digital UNIX, Solaris 8, Irix 6.5.recent and 
possibly others use "long" to mean 64 bits with the default ABI, but this 
lack of precision is just not helpful. I suspect that off_t will work 
provided we check that sizeof(off_t) == sizeof(off64_t). If not, I prefer the 
KIO::filesize_t (unsigned?) or perhaps KIO::offset_t (signed?) concept.

Thanks, Shaheed
