It was considered, but would limit (the initial version of) the
service to people with 'IP-capable' machines. Currently, that leaves
a lot of people out in the dark.
Personally, I also don't think cmd-line email is such a terrible
thing.-/

I haven't tried it personally, but the experience of my colleague is
that it works, but leaves something to be desired in the performance
stakes. Low-speed IP/PPP is clunky enough already; adding a telnet
layer (and another IP layer) gives a bit too much wrapping around
your data for good response. In particular the telnet layer would be
likely to break traffic into a lot of small packets. But for
non-interactive traffic this doesn't make much difference, though; it
just slows things down.
