Hi,

Does this not break the maxim that the furthest you need to go to is  
the nearest igate? How would you propose to configure a tracker for  
this?

Surely though, this then should be a function of the 'Network' i.e.  
the Digi and not the tracker.  It only means changing the code in  
every Digi (not trying to start an argument now or anything), but it  
would mean that all trackers could avail of the facility as long as  
their UI-PATH wasn't complete nonsense in the first place.

Basically, I should be able to set my path to AUTO or something  
(DISCVR?), and the network then ensures that my packets make it as  
far as the nearest I-Gate, (or nearest Big High Digi, or whatever the  
sysops set the upper bound to be) and don't cause any more QRM.  Any  
misconfigured trackers could be 'controlled' at this point as well.

However, if I'm 'in the field'  for whatever reason, and I know I  
need to get through all the Digi's in the country (Ireland only has  
about 5 :) ) then I could specify WIDE1-1, WIDE2-1 or WIDE2-2 as my  
path.. and it would work as the normal WIDEn-n.

I hope that makes sense.
