254This (experimental) perl extension implements OnTheSpot editing. It does

289We use it to implement a "distributed selection mechanism", which just
290means that one command uploads the file to a remote server, and another
291reads it.
292
293The commands can be set using the C<URxvt.remote-selection.store> and
294C<URxvt.remote-selection.fetch> resources. The first should read the
295selection to store from STDIN (always in UTF-8), the second should provide
296the selection data on STDOUT (also in UTF-8).

298The defaults (which are likely useless to you) use rsh and cat:
