Leider hat der Entwickler des Flyer Internet Modems (http://www.retroswitch.com/products/flyer/) Brandon Bogle entschieden, keine weiteren Updates mehr dafür zu entwickeln 
Evtl. wird er aber die Software dafür als Open Source rausgeben, sodass vielleicht andere die Software dafür weiterentwickeln.
Zudem ist er momentan aber an einem Nachfolgeprojekt:
Hier die Info von Brandon dazu:
I have started on a new version of the Flyer however. I'm using a much more powerful processor with more memory, which will allow me to add a lot more features such as SSL support.
I currently have a breadboard layout with most of the hardware in place. Code-wise, I have a new set of "foundation" code which will allow me to develop features much more rapidly. If you're a programmer (and interested), I can share more details if you like.
A small list of some planned features include full SSL support, more native internet protocol support (SMTP, FTP, etc), microSD, rs232 serial port with support for Hayes command set / ethernet-over-ip, and a web interface for Flyer configuration. Again, I can put together a long list if you like. I'm also trying to incorporate as many wish-list requests I've received from Flyer users, many of which just weren't possible with the existing Flyer (microSD support being an obvious one).
Es wird zwar noch ein paar Monde dauern, aber ich denke, dass das eine neue interessante Hardware für unseren kleinen C64 wird
