VLS had ASI input support, via the Linux driver for the Computer Modules
(http://www.computermodules.com/) cards. The Computer Modules driver
just exports a device file which, after configuration from an external
program, can be read like a standard UNIX FIFO (stream:/dev/asirx0).

The same drivers also support ASI output cards in pretty much the same
way. I expect that just writing to the device as if it was a file should
work as well, except if the driver expects some timing information. Even
in that case it shouldn't be difficult to write such a plug-in for VLC.
I do not have those output cards so I can't test.
