EGNOS and WAAS provide corrections from a geo-stationary satellites,
and do not need to do DGPS over the Internet.

The accuracy is improved, but not revolutionary.  I've been told that
the reliability has been improved too.  With EGNOS enabled, it is
possible to detect when the GPS position don't make sense.  I have not
verified that this is the case.
