Check out the dbHandleShared property on TIB_Connection. It is
designed to allow sharing a connection handle from a BDE acquired
connection. It seems to me that if that works you should also be able
to share the handle from other TIB_Connection instances. (But only
connect/disconnect using one instance.)

HOWEVER even if the above does work it may not be safe between
threads. There are threading issues in the IB/FB client library
(GDS32). A well known issue is that cpLocal connections are not
thread safe under any circumstances. GDS32 seems to be ok when using
network connections (even to localhost), but what impact there may be
in using the same connection handle between multiple threads I do not
know. Perhaps you could post a question to IB_Support.
