Then check out the new HIS 2004 web-cast series.  Modelled on the BizTalk Server 2004 series we ran earlier in the year you can learn how to bi-directionally plug into CICS and IMS applications, grab data from DB2 and expose it to the .NET Framework, use SSO to password sync across environments, use mainframe services as part of integration to BizTalk Server and all manner of interesting things.

Web-Casts start July 19th and more information is here.
