It would require significant changes to the way Osmosis works.  With some
effort, a new --rx task could perhaps be created to write read multiple XML
files and write them to separate pipes, but a new --merge task would have
no way of knowing how many inputs it should consume.

It's not something I'll personally be tackling.  Can this be solved with a
wrapper shell script?
