I was out of town for the last few days, and noticed this morning, thanks to Mike Chambers , that Macromedia has released a Flash Remoting Update SP1  which also includes updates to the Flash Remoting Components. Take a look at the list of Bug Fixes for the components.  I haven’t had a chance yet to update mine and try out some of the AMF-PHP services  I have been playing with, but will post later if I see any noticeable improvements or problems. Its worth noting also that I found out that there is already a project going to port the AMF-PHP project  to Perl, and its called FLAP – Flash Remoting in Perl  looks pretty nice already. If your a Perl fan definitely check it out.
