OK, I think this will be relatively straightforward (in principle). My
idea would be to create a new SqueezeIR protocol (called eg tcp). I
think it would be easiest to have each command in a seperate file and
put the filename into the existing SqueezeIR.xml file as
<command><value> values, otherwise SqueezeIR would have to parse the
xml and extract each command which would be tough. The ip and port
could be placed in <parameters> and the remote's protocol set as "tcp".
So far so good. There would need to be a tcpToNative() function called
from ProtocolToNative() that would read the file into SqueezeIR.
Problem here is that this would be asynchronous so might need callbacks
:(. The next step would be for StartTimer() and TimerCallback() to run
your code to send the http request instead of ir (using os.execute)
depending on the protocol name.
The bad news is that currently SqueezeIR doesn't keep the protocol name
once it has converted everything to the Native format so some work would
be needed there. A better option would be to have an ir/tcp flag for
each protocol to avoid having the protocol name hard-coded. Again some
work would be needed there. I don't think it will be beyond the realm
of the possible to implement your code but you'll have to wait until
I've got my system working again (waiting for some bits from eBay).
