What's wrong with a (very) slow link?  As long as there aren't any
queueing delays, the delay should be symmetric in both directions
and I'd expect ntpd to work OK.

Does 1 bd/sec overflow some of ntpd's assumptions?  Would it need
some minpoll tweaking?

Or maybe I should ask:  How slow a link is still useful?

These are my opinions, not necessarily my employer's.  I hate spam.
