hey!

yes, that is possible. You have to start a single instance
of midish and keep it running. Php scripts will have to
"connect" to midish and issue commands. 

This requires writing a simple wrapper that
accepts connetions (from php scripts) and writes the
received data on midish standard input.

There's an example program ``rmidish.c'' in the sources tar
ball. Basically you have to do something similar (actually
much simpler), but with a socket instead of the readline
library.

let me know it you have further questions!
