So, to answer the question : The target range for ET transmissions,
detectable at seti@home at 100LYs would be the following :

It's probably a bit optimistic expecting ET to be within 100 LY.

The Hiparcos catalog lists 2473 stars within 100.1 LY (32.5 mas) If the
stars last 10 billion years and a technical civilisation evolve on planets
around all of them, the technical civilisation has to last 4 million years
if one should always be detectable.

Maybee you should assume a distance of 1000-5000 LY.
