I would agree with others who suggest using some
sort of a SQL database. Flash could make a text file
for perl to parse. Have perl populate a local
sql database using a sql SEQUENCE to ensure non-dups.
I believe this could all be done with out a webserver
as long as each client has the standalone player.

That would get info into the data base. Using the
reverse...have perl create a text file from the database
for flash to use...would get info out of the database.
However...its been my exp...with flashplayer6 on linux
that flash is slow and awkward at displaying text on
the fly. I have a small example...

http://www.taproot.bz/~van (requires flash....duh)

this is swf pulling text from the "news letter" every
time its is viewd. Granted this is web-enabled...I think
its slow to build the movie...and the webserver is on my
LAN.
