This isn't really a better way but if you were going to go to all the trouble 
of setting up a 2nd TSM server then you could have one system backup itself and 
the other servers up through UNC.  Then create a backupset of that one node.  
If it is a bunch of 10 GB servers then they should backup incrementally, even 
with UNC, in little time.

Of course if you could run one backupset of multiple nodes to one tape that 
would be much better.

The (normal) environment is one backupset, one tape.

Possible workaround:
Create a second TSM server (or a second instance on the existing TSM
server) that uses a separate library (or possible a logical library
within your existing physical library).
Set up server-to-server communication, and use a server-based device
class to send backupsets to a virtual volume on the source server.
The target server will 'stack' multiple backupsets on a single physical
tape.
