The Southeastern website has an interesting new answer to the PAYG
acceptance question.

"10. Do you accept Oyster cards on your network?
We do already accept season tickets on Oyster on our network ( within
the valid zones) and while we do not yet accept Oyster Pre-Pay,
Southeastern announced its commitment to work with Transport for
London (TfL) to introduce Oyster Pay-As-You-Go (PAYG) on Southeastern
within two years. The implementation of PAYG will require significant
investment and Southeastern is working with TfL on issues such as the
need for additional validators at stations; the ability to sell and
top-up Oyster; and the possibility of installing automatic ticket
gates at some stations. There are still a number of issues to resolve
but we hope to implement Oyster PAYG on Southeastern by January 2009.

Oyster PAYG will not be cheaper than our usual rail fares."

I wonder if the last link hints at some of the issues surrounding PAYG
on Southeastern?
