Data Vendor Development Kit version 771

["Loewensteijn" <Loewensteijn@xxxxxxxxxxxx>]

I wonder if anyone knows if there is a later version of the Data Vendor 
Development Kit targeted at release 822. (SP5).
Sofar I have tested using Global Server release 771 against TradeStation 822 
and that works fine. Don't know yet if anything developped with the 
forementioned kit will work with Global Server release 822, perhaps someone 
can enlighten me what the differences are between the two Global Server 
versions (the executable files are not the same size so there are some 
changes - although the difference is only minimal so I do not think there 
are major changes).
On a further note: Has anyone considered / attempted replacing the 
underlying database engine with a later version? (Omega Research did not 
develop the engine themselves, they just repackaged an existing one which 
has gone through several revisions since then.)
My interest is that I would like to add some functionality to the database 
itself which can not be resolved by manipulating the incoming datastream.
Looking forward to some input on this subject, Marinus
