Sure, but zaptel can get the master sync from *one* of
the low-level drivers (e.g: a PRI card) and than it
would be hardware based.

Actually, that's exactly how zaptel works today.
The problem is that this sync is only used to synchronize
asterisk and not the other low-level drivers.
[there are some other minor problems. E.g: zaptel does not save
 the 'prefered' master parameter to zt_register() and so there
 is no predefined policy about sync master preference (e.g:
 PRI before FXS)]
