It also isn't true, at least not always. TagLib has multiple read modes
that read more or less of a file to trade off speed and accuracy. For
most files it would only need to read a very small amount of the file (a
few K, if that)...which is why people use it with SMB and NFS shares all
the time without an issue.

TagLib used to be entirely KDE independent; there are now some features
that use KDElibs that can be enabled at compile time. Given this, there
is certainly a possibility that kioslave support could be added;
however, it should be noted that this can't always be relied on to be
enabled (but this at least puts it into the distribution's corner).

TagLib 2.0 development hasn't started, but now is the time to be
thinking about changes to make. When 2.0 development starts I'll be
porting it over to some DVCS or another. I would email taglib-devel, not
contacting Scott Wheeler directly.
