Trying to answer some of my own questions. (please correct me if im wrong or
an unsafe route)
I should just mention that im using Indy v. 10
It seems the key to 1a) and 1d) would be to maintain a TThreadlist of
connected TIDContext's with their individual data.
1c) should then be possible to perform by getting the AContext from the
TThreadlist above and then a) either executing the AContext.OnRun event, or
b)even simpler by executing AContext.Connection.IOHandler.WriteLn()
Is the above understanding/approach correct and safe?
That leaves questions 1b), 2a), and 2b) open.
Cheers
Stephen
