[hpsdr] iPhone/iPad

[Chris Albertson]

If you'
ve giiven the phone away then the whole discussion is moot.

But I do have a few iPod touches in the house, but even so I really
dislike writing non-portable code.
I think you could do it using standard web protocols.  Is a waterfall
really the much different than watching live video?  It is not hard to
send 10 frame per second low-res video over a slow link and of course
audio is even easier.  Look at Apple's facetime app.  It sends live
video and audio between multiple hand held IOS devices and macs.  A
waterfall can't be harder than a live two way video phone.  Treat the
waterfall as a streaming video

I have a computer I run "headless".  It runs Linux but I have VMware
installed and inside a virtual machine I have Windows XP.  VMware on
Linux uses X11 to display the virtual PC's monitor.  X11 can be
transported over the network.  Last night I had a Windows XP based
program the was monitoring my GPS timing recever exported using X11.
I could watch it on anything that can run an x-server.    (VMware on
Linux makes Windows almost usable, much nicer then on bare hardware.)

VMware Server (free from the vmware web site) goes a step farther.  It
allows any "image" to run on any hardware and runs the display back to
your web browser.  So you can have virtual Windows XP, Win 7, Liux,
BSD or other and then you have a few computers and you can run those
on the computers and look at it all over the web.

Point is that, I think there is enough options to do what you want
already.  If the display runs on Linux, a Mac or Windows you an get it
to just about any other screen you own if you work at it.
