Mark, are you referring to an application like 
"IBM® Content Manager OnDemand for Multiplatforms"?
(see http://www-3.ibm.com/software/data/ondemand/mp/ )

The last time I looked at this, I saw that it did use TSM as a 2nd
level store, but it doesn't use the HSM client.  Instead it uses archive
and the product database keeps track of what documents are in what
archives.
