	The UK nearest equivalent to the ARPANET is JANET which links the
UK academic sites.  It is an X25 network.  We run login (X29), FTP, Mail, the
News and JTMP (Job Transfer and Management) over it.  It works just fine.
	Throughput through a switch will be several hundred megabytes a day.
If two hosts have 64K  bits-per-sec links I can easily manage 32K bps
throughput in the data transfer phase of FTP.
	How serious do I have to get?
