Thanks Ikai- Could I write a 'back-end' app as a web service app, then write various front-end apps for each agent/channel and make an app to app web service call?
Follow on question would be, how do I secure the back-end app interaction? Shared secret at deployment... openID for front-end apps... shared secrets at run-time... session management/tokens (poss using memcache in back-end app). Sorry if these are dumbie questions with answers in the docs somewhere. TIA again - John On Jun 15, 6:25 pm, "Ikai L (Google)" <[email protected]> wrote: > You can't access another app's datastore.
