I dont know of any flash server side software but it might be there
that can convert flv to ogg but it should be possible
flash recording from the client side onto the server is done using
flash media server but there is a open source alternative to it call
red5 (check up on it ) it is pretty good

--------------------------------------------------------------------------------\

well it is difficult to answer abt security issues as most issues can
creep up in the coding and might not be present in the platform java
is pretty secure but if you leave a vulnerability then u cant blame
java now can you ;) am not sure but communicating between a java
applet and javascript is possible


> * using a third party plugin/embedded object for recording ??
--------------------------------------------------------------------------

yes this option is there as there are many which provide this
functinality but it will be mostly a paid service not free


> * Writing my own Firefox and IE and chrome plugin ??

--------------------------------------------------------------------

well no one can stop you from writing a plugin for firefox and IE :)
and about chrome well they dont yet have support for plugins but it is
planned in the future

wow this is some pretty deep stuff dude
acc to me with my limited understanding of your project based on this
questions my suggestions would be to stick to flash and it should give
you a stable platform for both desktop and browser

desktop via AIR

xmpp is a gr8 protocol

remember though in flash the file recorded on the server is a flv file
you will have to extract the audio out of it and encode
and i believe for java applet also it will be the same but java has
support for wav format and this will have to be converted into mp3 on
the server or ogg format

the only reason am suggesting flash is because it is present on more
computers now then java

also checked out your site you have nice dreams of yours mentioned
there good luck dancing on that stage someday :)
