[DUG] Delphi Callbacks using DataSnap

[Alister Christie]

I've been trying to work out how to do callbacks using DataSnap and I've 
been trying follow Xavier Pacheco tutorial 
<http://dn.codegear.com/tw/article/29539>.  However things have changed 
a little since Delphi 6, in particular the data types for parameters.  I 
guess I should probably ask if anyone here is an expert on COM before I 
attempt to phrase a question,

So are there any COM/DataSnap experts out there?
