Any of those would be nice.  Nicer would be something adaptive, but=20
that's a pipe dream, I know.  I'm aware of the technological limitations=20

spectrum is divided, etc.

The difference between 10/.5 and 5.25/5.25 on the download would be=20
minimal (half as fast); on the upload, not so minimal (ten times=20
faster).  But even a 'less asymmetrical' connection would be better than=20
a 20:1 ratio.  4:1 (with 10Mb/s aggregate) would be better than 20:1.
