Sounds like adding a flush onto trajectory writes and writing a custom
plugin for VMD/pymol/whatever that updates the current display when the
file timestamp changes should be simple and good enough for your
purpose... You'd want to be sure that the extra I/O burden was
worthwhile - be that a buffered file-system write or your xml-rpc idea.
