You should be able to do this using the "urlappend" parameter to the  
handle proxy.  The example above would look  like this:

  http://hdl.handle.net/some/handle?urlappend=sequenceID% 
3DSEQUENCE_ID%26bitstreamName=FILENAME

Of course this brings up the question if your bitstream needs to be  
independently addressable, maybe it deserves its own object or  
identifier?

Thanks,
Sean
