Regarding the loss of AppleTalk connections when the Portable
goes to sleep, I can't see any fix for this. (But if any
genius comes up with one, I'd *love* to hear about it,
as my boss has the same trouble with NCSA Telnet on his Portable!)

Network connections are kept alive by both ends sending each
other data at periodic intervals. Even when they haven't
actually got anything to say to each other, they still exchange
"Are you there/yes I am"-type messages. The formats and
contents of the messages depend on the particular network
protocols involved (and there are lots of them). So there's
no easy way you could delegate the function of exchanging them
to some chip that keeps running while the rest of the machine
goes to sleep.

Mac keyboards shouldn't have caps lock keys. Caps lock is a mode.
