For clients in lurk (or lurkonly) mode, what I'm planning to do is to
manually set the DES buffer size to 1:1 whenever I connect (block size
chosen to take about 10min/block) and back to a few hours worth of blocks
before disconnecting.

This is because the client will try to keep the buffer full whenever it
detects a dialup connection, so there's no point in letting extra blocks
wait in the buffer. The reason this has to be done manually is simple -
the client doesn't know in advance when I'm going to hang up. (Doesn't
mean it couldn't be made a lot easier..)
