4) If ftp connect fails, try to ping NHC ftp site.  If ping works, repeat
   ftp connect a few times, at 10 second intervals until it either works
   or a counter runs out.  Then give more useful error message.  If ping
   fails (try other sites, too at that point to narrow down the problem),
   give error message.

6) Try to figure out a way to *AUTOMATICALLY* merge TS/TD track files.
