Assuming that you will have both machines up and running in the same
room or fairly close, asynchronous transfer may not be as bad as you
make it out to be.

You can connect the two machines together at 19200 baud, and then
transferring 20MB of data via YMODEM should take between 3 and 4 hours.
(my formula gets 8,333 seconds x 1.8 for handshaking time, but it's
usually a little high at 19200 baud.)  

If you can compress the data any, it will save time, and if you can
figure out how to get terminals running at 38,400 baud, you cut the
time by 40%.

In other words, it's about a half day of work.  Unfortunately, in my
(admittedly limited unix) experience, you could spend AT LEAST that
much time mucking around with tapes, and still not get it working :-(
