Linked servers

Good morning,
I'm looking for some direction in creating new Ms Access database that would
have linked tables to MSSQL 2005 ent. and in addition would be able to take
advantage of DB2 database that is linked in MSSQL. What I would like to do is
look up some values in linked DB2 tables while user is creating record in
MSSQL to validate it and then at the end of the batch(bunch of related
records) I would "push" that batch to temporary processing table on Mainframe
where DB2 folks would do something with these batches/records and send me a
response back. I have created linked server to DB2 using IBM OLE DB provider
for DB2 (IBMDADB2) and that is working, what I'm not sure of doing is linking
DB2 tables in MS Access DB.
I'm trying to all this in order to avoid installing DB2 Connect software on
each machine and configuring it on each machine that would need to use this
database. I would rather that server that has MSSQL talks to Mainframe
instead each individual computer.
I hope I explained it well... also if MS Access wouldn't be able to do this
please let me know if VB would.

Thanks

Amir
