[TYPO3-dev] to eID or not to eID?

[Lina Wolf]

As far as I understand the eID was developed to create quicker response, for 
example in surrounding of Ajax. The advantage of the eID would be that a lot 
of things that are usually initialised don't need to be in case of using 
eID.

But if I do need the full program in my Ajax response: typolinks, therefore 
a cObject, Typoscript, therefore the whole TypoScript building process, 
localised strings, therfore...

Is there still a real advantage in using eID then? Is there any advantage in 
using the alternative (witch would be page types?)

Would you suggest to use eID in pingback responses, XML-RPC and other 
not-Ajax maschine to maschine communication? Should XML's like RSS-Feeds or 
FOAF-XML be page types or eID?
