  It has been shown in recent analyses by ALEPH [1] and OPAL [2] that precision
QCD tests are possible with hadronic tau decays by comparing spectral moments
of the hadronic decay ratio of the tau with QCD calculations. In principle e+e-
data can be used in a similar manner by evaluating spectral moments of R. The
current e+e- data is compared with the OPAL tau data and a prediction is made
on the achievable accuracy of QCD tests with the projected precision of PEP-N
[3].
