My goal in all this is to not have to install applications on computers
anymore. Everything would be done through the browser interface. Even USB
is now becoming a pain. There's now the WinQual stuff on USB drivers that
we have to deal with. So far, it's been telling customers how to stand on
their heads to get around it, but we'll probably have to go through the
process of getting Microsoft approval on our USB drivers. The great thing
about Ethernet and Wi-Fi is that you don't need to install anything. It
just works. And the browser is the universal interface at this point. It's
OS independent and just works (pretty much - I'm having fun with HTML5
audio on various devices). Several of the products I've done now have ONLY
Ethernet interface. MUCH simpler!

It's been a while since I touched the code on the PIC18 device I did
Ethernet on. But, the PIC24 and PIC32 have had no shortage of flash. I can
always manage to use up RAM, but flash (where the web pages, javascript,
etc.) is held seems plentiful.
