X10 Computer Interface

[Dave <dju@xxxxxxxxxxxxxx>]

Hi,

I'm authoring a video motion detector application and would
really like to be able to send commands to X10 devices from
the user's PC if motion is detected.

Is there an interface that a third party app developer can
support in their software that will have some longevity? In
other words, do the X10 computer interfaces that are
currently available have any likeliness that they'll be
around in 5 years. I wouldn't want to support something then
have to explain shortly afterwards that the X10 feature is
no longer usable.

Would appreciate it if anyone can tell me which are the most
popular X10 computer interfaces. I used to have an X10
system when I had a house and the box I had (made by X10)
connected to the serial port of the PC. Now they probably
have something that uses USB. I hope so. I need to either
pick an existing device and declare that I support it or I
need to make my own hardware. The problem with that is that
it no longer becomes software only and the Internet cannot
be used to send hardware to the user..., let alone having to
make the x10 adapters too. BTW: The Parallax Stamp chips can
provide an X10 interface for anyone who wants to fiddle with
programming them.

Thanks for any help.

Dave
