Another alternative is to make better use of the downlink so that everyone
receives lots of data without everyone having to have an uplink.  The
current MIR TNC can downlink five periodic beacons.  One could be the
latest ONE-LINE keps for the MIR (instead of the current MESSAGE which you
have to log on inorder to copy).  Another could be the latest STATUS fromt
he crew.  Another could announce other things.  THis way everyone sees
something and not everyone needs to connect to ask for messages....

Software tracking programs could monitor the downlink and pick up a copy
of the latest keps automatically.  MIR would only need to send the
one-line keps ONCE every  5 minutes (0.3% of channel capacity) to assure
that everyone gets a copy every now and then...  There is a NASA standard
for sending one-line keps.  We should use it effeciently in this manner
for example...
