Kings Cross from Finsbury Park etc etc - in all of these cases (and
many others) where one must exit and re-enter through gates the
Oyster
system merely counts it as a continuation of the original journey.

This kind of progress and integration more and more shows up the
unfairness and illogic of buses still charging per vehicle instead of
per journey.

After 1900 and at the weekends I can make a journey across London on
three different systems: NR, LU and DLR, that is cheaper than catching
two buses, let alone how many it would take to cover the same distance
in a slower and less comfortable way.

Given the £3.00 Bus cap this isn't a big deal.

However the problem will be rather more visible when tube 9:30-16:00
counts as Off-peak from January 2009 :

Visitors and Londoners on lower incomes will also benefit from the
introduction of a new daytime off-peak and reduced fare on the Tube,
from 9.30am to 4.00pm Monday to Friday.

but it's difficult to fix without requiring bus interchangers to touch
out and/ or effectively charging extra when a bus journey took more
than 60 minutes or you didn't touch in on another within 30 minutes.
Using a "2 hour for the journey" rule like the tube have be much the
same problem given the large variance in timing for journeys by bus.
