Are we still talking about people attending MeetMe conferences with laptops
but without headsets? If so:

Personally I doubt that a 64ms echo can will help you with this issue. I
have not yet measured this but am willing to bet that the echo produced by
such a speaker/mic setup will exceed 64 and even 128ms. Perhaps you might
want to record a test and have a look at the WAV file to at least get an
idea of how long the echo really is before you invest in any sort of echo
can hardware. You might very well find out that your only option are
headets.


Kind regards,
